Question

a man moves on a straight horizontal road with a block
of mass 2 kg in his hand. If he covers a distance of
40 m with an acceleration of 1 m per sec.
find the work done by the man.
​

Answer 1

Answer:

80

Explanation:

mass=2kg. acceleration=1m/s*2

distance travelled=40m

work= force X distance----->1

force =mass X acceleration=2 X 1= 2N

substituting force in 1:

work= force X distance

work=2 X 40m

w=80J
