hi mani jha, can i wait for ur answer

anonymous · Answer

are u there

mani_jha · Answer

Good. Now, the ground will exert such a force on the object such that its speed becomes zero. And the object will exert the same force on the ground.
Such a force acts for a very small time, and is known as an impulse.
You've to find the force;
Force=(change in momentum)/time
 I am starting to think that the time should've been given.
