A frictionless plane is 10.0 m long and inclined at 33.0. A sled starts at the bottom with an initial speed of 4.30 m/s up the incline. When the sled reaches the point at which it momentarily stops, a second sled is released from the top of the incline with an initial speed vi. Both sleds reach the bottom of the incline at the same moment.
(a) Determine the distance that the first sled traveled up the incline.
1 m

(b) Determine the initial speed of the second sled.
2 m/s
