Question

a force of 100N acts on a block of mass 2Kg .the average resistive force is acting on the block is 50N. determine the change in kinetic energy of block as it moves by 5 m​

Answer 1

Answer:

change is 500

Explanation:

use f=ma

u will get acceleration

thensubstitute in v^2-u^2=2as

where u=0

u will get v

kinetic energy=1/2mv^2
