(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 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.
______m
b) Determine the initial speed of the second sled.
_______ m/s
the acceleration is
directed down the incline
a)
the time for the sled projected up the incline to come to rest is
The distance the sled travels up the incline in this time is
b)
The initial velocity is found from
the initial speed of the second sled is down the incline.
