Question
1. A car is traveling at a constant speed of 8 m/s. If the snow is falling at 3.1 m/s with an angle of 36
1. A car is traveling at a constant speed of 8 m/s. If the snow is falling at 3.1 m/s with an angle of 36 degrees to the vertical line toward the windshield, determine the velocity of the snow as seen by the driver.
Provide your answer in m/s. Round to the nearest two decimal places.
2. A golfer hits a ball, giving it a maximum height of 20 m. If the ball lands 112 m away at the level from which he hit it, how long does it take for the ball to reach maximum height. (Neglect air resistance.)
Provide your answer in s and round to the nearest two decimal places.
3. A golfer hits a ball, giving it a maximum height of 21 m. If the ball lands 116 m away at the level from which he hit it, what was its initial velocity in the horizontal direction (Neglect air resistance.)
Provide answer in m/s and round to the nearest one decimal place.
4. If the golf ball has horizontal velocity of 9.0 m/s and vertical velocity of 5.0 m/s, what is the golf ball's resultant velocity?
Provide answer in m/s and round to the nearest one decimal place.
5. Pulleys C and D in Figure are fastened together. Weights A and B are supported by ropes wound around the pulleys as shown. The radius for pulley C is 175 mm and the radius for pulley D is 137 mm.
If weight A is accelerating downward at 3.8 m/s2, determine the angular acceleration of pulleys C and D.
Provide your answer in rad/s2 and round to the nearest one decimal place.
6. Pulleys C and D in Figure are fastened together. Weights A and B are supported by ropes wound around the pulleys as shown. The radius for pulley C is 185 mm and the radius for pulley D is 110 mm.
If weight A is accelerating downward at 2.5 m/s2, determine the linear acceleration of weight B.
Provide your answer in m/s2 and round to the nearest two decimal places.
7. A train with a maximum speed of 105 km/h has an acceleration rate of 0.16 m/s2 and a deceleration rate of 0.63 m/s2.
If the train covers 1500 m while accelerating to maximum speed from rest, how long does this take?
Provide your answer in s and round to one decimal place.
8. A train with a maximum speed of 105 km/h has an acceleration rate of 0.74 m/s2 and a deceleration rate of 0.88 m/s2.
If the train takes 50 s to slow down from maximum speed to a complete stop, how much distance does it cover during this process?
Provide your answer in m and round to the nearest whole number.
