(Please explain briefly)

A frictionless plane is 10.0 m long and inclined at 28.0°. A sled starts at the bottom with an initial speed of 5.70 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 v_i. Both sleds reach the bottom of the incline at the same moment.

(a) Determine the distance that the first sled traveled up the incline.

______m

b) Determine the initial speed of the second sled.

_______ m/s
