Required information You are driving your car along a country road at a speed of You are driving your car along a country road at a speed of 24.5 m/s. As you come over the crest of a hill, you notice a 24.5 m/s. As you come over the crest of a hill, you notice a farm tractor 25.0 m ahead of you on the road, moving in the farm tractor 25.0 m ahead of you on the road, moving in the same direction as you at a speed of 10.0 m/s. You immediately same direction as you at a speed of 10.0 m/s. You immediate slam on your brakes and slow down with a constant slam on your brakes and slow down with a constant acceleration of magnitude 7.80 m/s. acceleration of magnitude 7.80 m/s. How far will you travel before you stop the car? How far is the tractor in front of you when you finally stop? m mRequired information Required information A locust jumps at an angle of 55.0 and lands 0.750 m from A locust jumps at an angle of 55.0 and lands 0.750 m from where it jumped. where it jumped. What is the maximum height of the locust during its jump? Ignore air resistance. If it jumps with the same initial speed at an angle of 45.0, the maximum height would be cm Multiple Choice O slightly larger. O the same.Required information A locust jumps at an angle of 55.0 and lands 0.750 m from where it jumped. If it jumps with the same initial speed at an angle of 45.0', the range would be Multiple Choice O two times smaller than the initial range. O slightly smaller than the initial range.Required information A skier with a mass of 63.0 kg starts from rest and skis clown an icy (frictionless) slope that has a length of 210 m at an angle of 32.0\" with respect to the horizontal. At the bottom of the slope, the path levels out and becomes horizontal, the snow becomes less icy, and the skier begins to slow down, coming to rest in a distance of133 m along the horizontal path. What is the speed of the skier at the bottom of the slope? E m Required information A skier with a mass of 63.0 kg starts from rest and skis clown an icy {frictionless} slope that has a length of 210 m at an angle of 32.0\" with respect to the horizontal. At the bottom of the slope, the path levels out and becomes horizontal, the snolar becomes less icy, and the skier begins to slow down, coming to rest in a distance of133 m along the horizontal path. What is the coefficient of kinetic friction between the skier and the horizontal sunace? E Required information A model rocket is fired vertically from rest. It has a constant acceleration of 14.4 m/s for the first 1.50 s. Then its fuel is exhausted, and it is in free fall. The rocket has a mass of 91.0 g; the mass of the fuel is much less than 91.0 g. Ignore air resistance. What is the upward net force on the rocket during the first 1.50 s after liftoff? NRequired information A model rocket is fired vertically from rest. It has a constant acceleration of 14.4 m/s for the first 1.50 s. Then its fuel is exhausted, and it is in free fall. The rocket has a mass of 91.0 g; the mass of the fuel is much less than 91.0 g. Ignore air resistance. What is the upward force exerted on the rocket by the burning fuel? NRequired information A model rocket is fired vertically from rest. It has a constant acceleration of 14.4 m/s- for the first 1.50 s. Then its fuel is exhausted, and it is in free fall. The rocket has a mass of 91.0 g; the mass of the fuel is much less than 91.0 g. Ignore air resistance. How high does the rocket travel? mRequired information A model rocket is fired vertically from rest. It has a constant acceleration of 14.4 mils2 for the first 1.50 s. Then its fuel is exhausted, and it is in free fall. The rocket has a mass of 91.0 g; the mass of the fuel is much less than 91.0 g. Ignore air resistance. Howr long after liftoff does the rocket return to the ground? :5 Required information A model rocket is fired vertically from rest. It has a constant acceleration of 17.5 rnfs2 for the first 1.50 s. Then its fuel is exhausted, and it is in free fall. The rocket has a mass of 810 g; the mass of the fuel is much less than 810 g. Ignore air resistance. Identify the graph showing the rocket's vertical velocity vs. time from launch until it returns to the ground. Multiple Choice 11-..- \fRequired information Superman is standing 204 m horizontally away from Lois Lane. A villain drops a rock from 4.00 m directly above Lois. If Superman is to intervene and catch the rock just before it hits Lois, what should be his minimum constant acceleration? If the acceleration is toward Lois, enter a positive value. If the acceleration is away from Lois, enter a negative value. m/s 2Required information Superman is standing 204 m horizontally away from Lois Lane. A villain drops a rock from 4.00 m directly above Lois. How fast will Superman be traveling when he reaches Lois? m/s
