Answer:

360 W.

Explanation:

The\;formula\;to\;find\;the\;Power\;is: P=Fv

In which,

P = Power.

F = Force.

v = velocity.

So, we have to apply values in the formula.

         P=Fv

         F=10\times(10+2)N

         F=120N

         v=3\;m/s\;that\;is\;already\;given

Then,\;\;\;\;\;\;\;\;\;P=120\times3=360W

So, the following answer is correct according to the explanation.

Damm [24]

Answer:

Time taken t = 4.167 seconds (Approx)

Explanation:

Given:

Initial Speed u = 12 m/s

Final speed v = 0 m/s

Acceleration a = -50 m/s²

Find:

Time taken t

Computation:

v = u + at

0 = 12 + (-50)t

t = 4.167 s

Time taken t = 4.167 seconds (Approx)
