Work, Energy and Power Report Error

A

Power developed by this force varies linearly with time.

B

Power developed by this force varies parabolically with time.

C

Power developed by this force varies linearly with displacement.

D

Power developed by this force varies parabolically with displacement.

Solution:

Power developed by a force acting on a body is . If constant we can use so we get and we can use displacement of body as .
