7) In the diagram below, a cart is released from rest at a distance x1 from the first of two photogates. The cart then rolls down the ramp through both photogates. The distance between the photogates is x2. For this problem, you may assume that the cart is frictionless and the acceleration of the cart a = g sin θ.
a) If x1 = 20 cm, x2 = 50 cm, and θ = 20°, what is the average velocity of the cart between the photogates (over the distance x2)?
b) If x1 is reduced to 19 cm and everything remains the same, what is the average velocity of the cart between the photogates (over the distance x2)?

A 500 g cart is released from rest 1.00 m from the bottom of a
frictionless, 30.0? ramp. The cart rolls down the ramp and bounces
off a rubber block at the bottom. The figure (Figure 1) shows the
force during the collision.
After the cart bounces, how far does it roll back up the
ramp?

A cart starts at rest and rolls down a ramp as shown below. Gravity causes the cart to have a constant acceleration as it travels along the ramp. When it reaches the bottom of the ramp, friction with the flat surface causes it to gradually slow to a stop Draw graphs of the acceleration, velocity, and position of the cart throughout its motion as a function of time. The graphs should be laid out as they were on the computer...

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 box of mass m is released from rest on a frictionless slope as depicted on the left of the figure below. The slope is at an angle theta. From this information, calculate the acceleration of the box as it slides down the ramp. Next consider a uniform solid cylinder of radius R placed on a slope with the same angle theta as shown on the right of the figure above. When the cylinder is released from rest, it rolls without slip down the ramp. Calculate the acceleration...

A 19.0-kg block is released from rest on a frictionless 35.0 incline. Below the block is a spring that can be compressed 3.60 cm by a force of 270 N. After the block is released, the block slides down the frictionless ramp and compresses the spring by 5.50 cm. How fast is the block traveling the moment it reaches the spring?
