Question

block of mass 10 kg slides on a horizontal road against friction with initial speed 216 km/h. If it stops

finally, then evaluate the work done by friction?​

Answer 1

Explanation:

Answer

Initial velocity of block A is 10 m/s, and it will decrease after keeping it on B due the friction force between both the blocks.

Retardation of block A due friction (a ) = −μg

Velocity of A at any time t

Answer 2

Answer:

vb=5m/s answer of question
