Answer:

25 N; 250 W.

Explanation: Work Done

=

Force

×

Displacement

×

cos

(

The angle between Force and Displacement

)

So, Let's Assume the Force to be

x

Newtons.

So, According to The Sum,

×

x

x

⋅

100

=

2500

⇒

x

=

25

00

1

00

=

25

So, The force was

25

N

.

And, We also know,

Power

=

Work Done

Time

So,

The Power of the Machine =

2500

10

Watts

=

250

Watts
