Two object are initially at rest on a frictionless surface. Object 1 has a greater mass than object 2. The same constant force start to act on each object. The force is removed from each object after it accelerates over a distance d. after the force is removed from both objects, which statement is correct (p:momentum, K: kinetic energy)?

A

`p_1ltp_2`

B

`p_1gtp_2`

C

`K_1gtK_2`

D

`K_1ltK_2`

Text Solution

Verified by Experts

The correct Answer is:
B
From work energy theorem
`Fd=k_f-K_i=K_f`
so `K_1=K_2`
`m_1gtm_2`
`p_1gtp_2`
