A frictionless plane is 9.4 m long and inclined at 31.9. A sled starts at the bottom with an initial speed of 5.03 m/s up the incline. When it reaches the point at which it momentarily stops, a second sled is released from the top of this incline with an initial speed vi . Both sleds reach the bottom of the incline at the same moment.The acceleration of gravity is 9.8 m/s2 .

a. Find the distance that the first sled traveled up the incline.

b. Find the initial speed of the second sled.
