Question

e) An engine of power 200 W, operates for 4 s. The force developed by the engine is
100 N. The choose the work done by the engine and maximum displacement caused
by the force from the following
(1) 600 J, 6m (2) 800 J , 8m (3) 100 J ,10m (4) 500 J, 5 m [2]​

Answer 1

Answer:

option 2

Step-by-step explanation:

given that..

power = 200w

time = 4 s

force = 100N

power = work done / time

==> work done = power × time

                         = 200 × 4

                         = 800 J

also we know..

work done =  force × displacement

==> displacement = work / force

                              = 800 / 100

                              = 8m

Answer 2

Answer:

the answer is sufficient
