A 0.5 kg cart starts from rest at the top of a ramp that is at 30 degrees above the horizontal. At the bottom of the ramp is another 0.75 kg cart at rest. The 0.5 kg cart rolls down the ramp and collides with the 0.75 cart after which they become stuck together and move along the level ground at a speed of 3.1 m/s. At what height did the 0.5 kg cart start from? (Neglect friction)

A 1.0-kg standard cart collides on a low-friction track with cart A. The standard cart has an initial x component of velocity of +0.40 m/s, and cart A is initially at rest. After the collision the x component of velocity of the standard cart is +0.20 m/s and the x component of velocity of cart A is +0.65 m/s . After the collision, cart A continues to the end of the track and rebounds with its speed unchanged. Before the...

A sled starts from rest at the top of a hill and slides down with a constant acceleration. At some later time the sled passes a red flag stuck into the snow at an unknown distance from the top of the hill; 2.00 s after passing the red flag the sled is 15.91 m m past the red flag; and another 2.00 s later, the sled is now 37.63 m m past the red flag. A. I found the acceleration to be...

PLEASE ANSWER CORRECTLY THE CORRECT ANSWER IS 46 A roller coaster cart starts at the top of a quarter circular hill (no friction) of some radius at a speed of 11.8 m/s. At the bottom of the hill it encounters a horizontal surface with friction and the coefficient of kinetic friction is 0.55. It travels over that horizontal surface for 8 meters and encounters a frictionless loop with a radius of 23 meters. If it is to just barely make...
