Suppose there is friction on the cart in procedure 1, as the cart is traveling up the incline. What is expected for the mechanical energy of the cart?
It depends on the choice of the zero for the potential energy.
The energy at the top should be greater than the energy at the bottom.
The energy at the top should be equal to the energy at the bottom.
The energy at the top should be less than the energy at the bottom.
Homework Answers
The energy at top should be less than energy at bottom because some amount of energy is lost to overcome frictional force

A 0.2 kg plastic cart and a 20 kg lead cart both roll without friction on a horizontal surface. Equal forces are used to push both carts forward a distance of 1 m, starting from rest. After traveling 1 m, is the kinetic energy of the plastic cart greater than, less than or equal to the kinetic energy of the lead cart? Explain. Match the words in the left column to the appropriate blanks in the sentences on the right....

3. Look at the picture above. How far down the incline from the
motion sensor is the zero point of potential energy?
Xuo is 2.2 meters away as measured from sensor toward bottom of
track.
The value for Xuo will be set to distance from sensor to closest
edge of cart when cart is at rest at bottom of track.

1. A 185 g cart is given a quick push up a frictionless incline, giving it an initial velocity of 1.45 m/s. The incline is at an angle of 10.0 to the horizontal. You must show your work to get full credit for this problem. a) What is the cart's initial kinetic energy, i.e. when it leaves the launcher? KE =mv eay @ztty =C85k9)(145s) = .1343 b) What is the cart's change in kinetic energy (Kr-Ko) from the launch point...

1) A cart for hauling ore out of a gold mine has a mass of 447 kg, including its load. The cart runs along a straight stretch of track that climbs a shallow 4.63∘ incline. A donkey, which is trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 436 N force for a distance of 115 m by means of a rope that is parallel to the...

Part 1) A small block travels up a frictionless incline that is at an angle of 30.0°above the horizontal. The block has speed 4.26 m/s at the bottom of the incline. Assume g = 9.80 m/s2. How far up the incline (measured parallel to the surface of the incline) does the block travel before it starts to slide back down? Part 2) Complete the following exercises. (Assume g = 9.80 m/s2.) (a) A small block is released from rest at...

h 5. A cart rolls with negligible friction down a ramp that is inclined at an 8 = 32' above level ground. It is released from rest at a height h = 52 cm. What we want to do is to figure out how fast the cart will go when it reaches the bottom of the ramp. Let's begin by establishing the equations that model the motion of the cart. Recall that we are dealing here with an example of...

TUDUNUL AP Callegard AP Physics 1 FeburaryExamReview 24. A block of mass M is at rest on a ramp that is inclined at an angle with respect to the honzontal. Frictional forces are considered to be nonnegligible. The block is pushed against a spring and then held in place. The spring is compressed a distance of 21, and the spring is not secured to the block. The block is then released from rest, travels up the incline, and comes to...

Wrap up question 1: A box slides down a ramp at constant speed. Does the box experience friction? Explain using the ideas of balanced vs unbalanced forces. Wrap up question 2: Two carts are connected with a string. If you pull on the left cart to the left with a large force and your friend pulls on the right cart to the right with a small force, how will the force of the left cart pulling on the right cart...

The Sidewinder is a shuttle type steel rollercoaster. The rollercoaster cart starts at the bottom of the frictionless track and is accelerated from a stand still over a distance of 7 meters. Then the cart enters the loop, rises to the top with just enough velocity to keep from stalling at the top of the loop. Gaining velocity the cart finishes the loop, bottoms out, and then rises up the vertical segment of the track. After stalling out at a...
