Question

A constant force of 10N causes a box to move at a constant speed of 2 m/s. How much work is done in 10 seconds?​

Answer 1

hey friend your answer↓

displacement= speed×time=2×10=20m

work done=force×displacement

=10×20

=200 J

hope it helps you!

Answer 2

Answer:

The work done by the force in 10 sec is 200 J.

Explanation:

Given,

The constant force acting on the body (F) = 10 N

The constant velocity with which the body is moving (v) = 2 m/s

Time (t) = 10 sec

To find,

Work done by the force in time 10 sec (W).

Calculation,

We know that the power of the body(P) is:
P = Work done per unit time

P = W/t...(1)

But also power is defined as:

P = F × V...(2)

Now substitute equation (1) in (2) we get:
W/t = FV

⇒ W = F × V × t

⇒ W = 10 × 2 × 10

⇒ W = 200 J

Therefore, the work done by the force in 10 sec is 200 J.
