Question

.Aforce of 1000N was applied to stop a car that was moving with a constant velocity.The car stopped after moving through10 M.How much work is done?​

Answer 1

Answer:

-100000 joules

Explanation:

formula: work done=f.dcos(angle)

w=1000.10cos(-180°) (because force is in opposite direction which means workdone is minimum i.e is negative)

w=100000(-1) (since cos 180° is equals to -1)

w= -100000 Joules.
