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...

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...

a block with a mass of 2.5 kg starts from rest at the top of the
apparatus shown below. it then slides without friction down the
incline, and collides with a spring attached to a wall. The spring
has a spring constant of K=120N/m. Using the principle of energy
conservation,
a. find the initial gravitational potential energy of the block
at point A
b. find the kinetic energy of the block at point B
c. what is the velocity of...

4. Energy and Momentum for 15 points: A 200 gram lab cart is initially at rest on top of a 50 cm ramp, as shown. Note that the wheels are very light and the axle has no friction in it. You push the cart as it moves through a distance of 20 cm with a constant force of 10N in a direction oriented 20 degrees below horizontal. After you stop pushing on the cart, it encounters a ramp, and rolls...
A solid cylinder of radius R and mass m, and moment of inertia mR2/2, starts from rest and rolls down a hill without slipping.
A solid cylinder of radius R and mass m, and moment of inertia mR2/2, starts from rest and rolls down a hill without slipping. At the bottom of the hill, the speed of the center of mass is 4.7 m/sec. A hollow cylinder (moment of inertia mR2) with the same mass and same radius also rolls down the same hill starting from rest. What is the speed of the center of mass of the hollow cylinder at the bottom of...
