A frictionless plane is 10.0 m long and inclined at 42.0°. A sled starts at the bottom with an initial speed of 4.60 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.
