The SI unit of power is the watt<span>, which is equal to one </span>joule/<span>per second.
So I would say Watt is the answer. Hope it helped. :)

Answer:
just find the answer in Google because I post it into Google
Multiply 200x10 then you will have your answer
From kinematic relation d = vi t + 1/2 at^2 , a = 2d/t^2 since it starts from rest . Acceleration does not depend on the mass. a = 2* 2.5 / (1.47)^2 = 2.3139 m/s^2.
Acceleration down the slide is due to the parallel component of gravity force. Friction opposes this force and acts up the inclined plane. mg sin theta - f = ma. Friction = f = (2.45 * 9.8) sin 30.5 - (2.45)(2.3139) = 6.5169 N.
Normal force = mg cos 30.5 = (2.45*9.8)* cos 30.5 = 20.6877 N. Friction = uk N. coefficient of friction = = friction / N = 6.5169 / 20.6877 = 0.32.
When it reaches the bottom of the slide, vf = vi + at = 0 + ( 2.3139)(1.47) = 3.4014 m/s = velocity at the bottom
<span> the </span>law of conservation of energy<span> states that the total </span>energy<span> of an isolated system remains constant it would be said to be conserved over time. </span>Energy<span> can neither be created nor destroyed but then rather, it transforms from one form to another.
hope this can help you ^_^</span>
