Question

A 16 pound bowling ball takes approximately 1 second to hit the ground when dropped from a height of 5 meters. The time it takes for an 8 pound bowling ball to fall under the same conditions is A. 1 second. B. 2 seconds. C. 3 seconds. D. 4 seconds. A truck is driving along a straight highway at a constant velocity. From this information we can conclude that A. the force from the engine is greater than the frictional forces. B. the static friction force from the tires is zero. C. there is a net force on the truck in the direction of its motion. D. the net force on the truck is zero.

Explanation / Answer

9. y = v0 t + a t^2 / 2

as we can see, time taken depends only on initial velocity, height and acc. due to gravity.

it is indepenedent of mass.

Ans: (A) 1 sec

10. constant velocity means a = 0

and Fnet = m a = 0

Ans(D)
