V QUESTION 1 Q1 Choose one . 5 points Which of the following is not a vector? O Velocity Weight O Friction O Density QUESTION 2 Q2 Choose one . 5 points Which of the following objects would have the largest inertia? A 10 kg block O A block that weighs 12N on Earth O 5 kg of water V QUESTION 3 Q3 Choose one . 5 points Which of the following is TRUE of free fall? O Fall rate depends on the shape of the object OFall rate depends on the mass of the object Air resistance is negligible O Terminal velocity would eventually be reachedQUESTION 4 Q4 Choose one . 5 points If a projectile has a starting horizontal velocity of 8m/s and vertical velocity of 2 m/s up, what will be the horizontal speed after 3 seconds? (Assume no air resistance and the projectile has not hit the ground) 2m/s O 8m/s 15m/s 27.4 m/s QUESTION 5 Q5 Choose one . 5 points An astroid with a mass of 1000kg is flying by the Earth with a mass of 5.97 * 1027kg . When they are 1 * 10m apart, what is the force of attraction due to gravity? 5.97*10^21 N 5.97*10^18 N 3.98*1048 N QUESTION 6 Q6 Choose one . 5 points A block that weighs 25 N is stationary on table and has a coefficient of static friction between them of 0.4. If a horizontal force of 8N is applied to the right, which will be true? O Static friction will apply a force of 8N on the block to the left O Static friction will apply a force of 10N on the block to the left The block will start to move O The block will blow upGROUP 7 Q7 Group . 4 questions This question has multiple parts that might require information calculated in one part to be used later in the problem. If this happens I will carry any mistakes through the problem so that missing one part will not cause you to miss other parts. For example, if in part A you calculate the answer to be 3.5 when it is really 4.7 then you will lose points for part A. If part B uses your answer from part A, I will calculate a new answer for B based on the 3.5 you got in A. This will prevent you from losing points for A and B from one mistake in A. Question 7: A cannonball is shot into the air from ground level. The cannon ball has an initial vertical velocity 75m/s and horizontal velocity of 15m/s. Ignore air resistance. QUESTION 7.1 07 A Response . 9 points What is the maximum height of the projectile in meters?QUESTION 7.2 Q7 B Response . 8 points How long will it take for the projectile to reach this maximum height in seconds?QUESTION 73 Q7 C Response . 6 points How long in seconds will the total flight of the projectile be in seconds?QUESTION 7.4 Q7 D Response . 9 points What will be the range of the shot in meters?GROUP & Q8 Group . 4 questions This question has multiple parts that might require information calculated in one part to be used later in the problem. If this happens I will carry any mistakes through the problem so that missing one part will not cause you to miss other parts. Question 8: A 20kg cardboard box is being pushed across the floor with an applied horizontal force of 200 N. The coefficient of kinetic friction between the box and floor is 0.25. Ignore air resistance, but not friction with the ground. QUESTION 8.1 Q8 A Choose all that apply . 8 points Which of the following forces are acting on the box? (Select all that apply) _ Centripetal force Normal force Gravity Tension Friction QUESTION 8.2 BB Response . 10 points How much force is the friction applying? (in Newtons)QUESTION 83 8C Response . 10 points What is the acceleration of the box (in m/s^2)?QUESTION 8.4 8 D Response . 10 points How fast will the box be moving after being pushed across flat ground for a distance of 12m (in m/s)
