A toy car slides down a slope. If the top of the slope is 2m higher than the foot of the slope, how fast will the car be moving when it reaches the foot? (Assume that all of its g.p.e is transformed to k.e?

Assuming there are no energy losses due to friction or drag, the gravitational potential energy will change into kinetic potential energy as the car reaches the bottom of the slope. G.P.E = m*g*h K.E = (m*v^2)/2 where m = mass of toy car (kg) g = gravity (m/s^2) h = heigh of your car from the bottom (m) v = velocity of the toy car as it reaches the bottom (m/s) Equate K.E to G.P.E G.P.E =... more
