Question

A block of mass 1 kg is at rest on a smooth horizantal surface a horizantal force of magnitude 4 n starts acting on a block if tge kinetic energy of the block when it has been displaced by 4 m due to the force is x joul find the value of x​

Answer 1

Answer:

16 joules

Explanation:

Work energy theorem says Change in kinetic energy=Work done by all forces on body .

In the given situation body is acted upon by 1 force of mag 4N .so W=4×4=16 .

So gain in KE=16J

Hope this helps :)
