Question

light but both the same size, roll off of a horizontal table at the same speed. Which one from the base of the table? Ignore are resistance. sibling across the ice. The puck eventually stops away from the wall or any other barrier. This is most but because: the puck ran out of speed force acted or the puck which made it stop was acting on the puck the whole them the did not have any net force to keep it going and a 1 -kg mass are moving with speed 4.0 m/s. Both objects encounter the same constant braking object travels the greater distance before stopping? the 4.0-kg mass determined from the information given and 2m are in contact with each other on a surface. (See Fig. 4-3.) What is the answer x the more massive box?

Explanation / Answer

Here,

1) as the acceleration due to gravity is same on both the balls irrespective of their masses

both will travell same distance

hence, the correct option is C) both land the same distance away.

2)

as the puck is slowing down and it will stop in some time

hence, there must be some frictional force acting on the puck

C) a small friction force was acting on the puck the whole time

3)

for the same force , as the acceleration of 4 Kg is lower ,

hence , it will stop after more time , and will move a larger distance

the correct option is B) the 4 Kg mass

4)

for the acceleration of masses a

Using second law of motion

F = (3 * m) * a

a = F/(3m)

the acceleration of the massive box is F/(3m)
