Question

if a block of mass 2 kilogram is moving with a speed of 10 metre / second. find the amount of force need to stop in 5 seconds?​

Answer 1

Explanation:

Mass of block:- 2kg

Initial velocity of block:- 10 m/s

Final velocity of block:- 0 m/s (As the block stops)

Time to stop the block:- 5 sec.

Force required to stop the block:-

F = ma

F = 2 (0-10)/5

F = -20/5

F = -4 N

Therefore, force required to stop the block is -4N.

I hope my answer is correct and it helped you.
