I need the graph to be the full motion of the cart. From rolling down the incline at constant acceleration, to rolling onto a flat surface with friction and decelerating to a stop Gravity causes the cart to have a constant When it reaches the bottom of the ramp, friction with the flat ro n a ramp as acceleration as it travels along the ramp. surface causes it to gradually slow to a stop. O Draw graphs of the acceleration,...

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...

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)

20) A cart rolls with negligible friction on a ramp that is inclined at an 17 degree angle above level ground. It is released from rest and reaches the bottom of the ramp in 4 seconds. How far did it travel along the ramp? a) What was the vertical height from which the cart was released? b) At the bottom of the first ramp, the cart smoothly rolls onto a second ramp without losing any significant amount of speed. The...

Group Activity: Ball rolling down ramp and off cliff As shown in the figure below, a hollow ball with a mass m 5.00 kg and radius r -30.0cm starts from rest and rolls a distance of 1.2 m down a 30° ramp, before reaching a flat section at the bottom of the ramp. The ball then rolls along the flat section for 1.0 m before rolling off a 2.5 m-high cliff. The ball lands a distance d from the bottom...

As shown below (not to scale), a block of mass starts from rest
and slides down a frictionless ramp of height h. Upon reaching the
bottom of the ramp, it continues to slide across a flat
frictionless surface. It then crosses a "rough patch" on the
surface of length d=10m. This rough patch has a coefficient of
kinetic friction uK=.1. After crossing the rough patch, the block's
final speed is vf=2m/s. What is the height of the ramp? Hint: I...

A disk of m=5 kg and radius r=2 m starts from rest and rolls down a 20 degree incline from an initial height of 50 m. What is the linear velocity of the disk as it reaches the bottom of the incline? What is the rotational kinetic energy of the disk at the halfway point between the positions 1 and 2? If it takes 1.2 seconds for the disk to reach the bottom of the incline, find the magnitude of...

a skier starting from rest down a snow slope that makes 18 degrees with the horizontal. He starts from the height of 8 m. at the bottom of the slope is a 9 m long rough horizontal surface. the acceleration slowing the skier down on the rough patch has a magnitude of .8m/s2. what is the skier's speed when he reaches the end of the rough patch? calculate the time intervals it takes the skier to reach the bottom of...

1) You roll a ball up a ramp of length L and measure the amount of time for the ball to reach the top of the ramp to be At. Determine the magnitude of the acceleration of the ball in terms of the variables L and At only. (The symbolic answer for the magnitude of the acceleration will not contain the initial speed or the angle of incline.) For the physical representation (part 2a), draw a motion diagram and graphs...
