A small cart of mass 5 kg slides down from the top of acurved track of unknown length. It first passes a smallpatch of rough surface, and then it hits a spring of restlength 1.63 m and stops. The spring is also located on asecond patch of rough surface. If height of the curvedtrack is 1 m, what is the velocity of the cart in m/s afterpassing the rough patch with coefficient of kineticfriction 0.2 and distance 2.15 m?m00wwlkdWs

Given: m=5kg, h=1m, μ=0.2, d=2.15m The work done by friction on the cart is :…

Suppose you have a spring (of constant k = 250) and you compress it 10 cm. next to the spring you place a frictionless cart of mass 250 g. The spring is released and the cart is pushed along a horizontal track. What speed (in m/s) does the cart obtain?
A daredevil on a motorcycle leaves the end of a ramp with a speed of 29.0 m/s as in the figure below. If his speed is 27.3 m/s when he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance.
A 100kg werewolf slides 0.6m after being shot. If the coefficient of friction between the werewolf and the ground is 0.8, What was the werewolf’s speed when it began to slide? If the silver bullet had a speed of 350m/s when it hit the werewolf, what mass would it need to result in the werewolf’s slide?
As shown in the figure below, a 2.25 kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction ?k = 0.510. Find h (in m) such that the block's speed after crossing the rough patch is 3.60 m/s. (Enter a number.)?m
A horizontal force of 20 N pulls a block of mass 3.8 kg across a level floor. The coefficient of kinetic friction between the block and the floor is MK = 0.25. If the block begins with a speed of 6.0 m/s and is pulled for a distance of 18 m, what is the final speed of the block? m/s
