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 40-kg child slides down a curved slide starting at the top with an initial speed of 4 m/s. (a) Suppose that the slide is frictionless. Determine the speed of the child when she is 3 m below her starting height. (b) Suppose that the slide has friction. Determine the speed of the child when she is 5 m below her starting height if she starts from rest and 300 J of thermal energy is dissipated during the motion.

8. A 30.0-kg block slides down a frictionless incline. If the block starts from rest and has a speed of 3.00-m/s at the bottom, at what vertical distance did the block start its descent Answer: 0.459 m 9. It is found that a force of 18-N is required to stretch a spring by 0.300 meters from its natural length. (a) What is the spring constant of the spring? (b) How much energy is stored in the spring when it is...

A 2.7-kg block is released from rest and allowed to slide down a frictionless surface and into a spring. The far end of the spring is attached to a wall, as shown. The initial height of the block is 0.54 m above the lowest part of the slide and the spring constant is 453 N/m. (a) What is the block's speed when it is at a height of 0.25 m above the base of the slide? (b) How far is...

A block of mass m = 3.00 kg starts from the rest and slides down a 30.0∘ incline which is 3.60 m high. At the bottom, it strikes a block of mass M = 6.40 kg which is at rest on a horizontal surface (Figure 1). (Assume a smooth transition at the bottom of the incline.) The collision is elastic, and friction can be ignored. (A) Determine the speed of the block with mass m = 3.00 kg after the...

On a planet having g= 10m/s^2, a 2kg mass, starting from rest, slides down a frictionless in life on to a frictionless horizontal surface. The speed of the mass on the horizontal surface is 10m/s. A) Determine the height h at which the box began its slide. consider again the same frictionless incline. However, upon reaching the horizontal surface, a surface having friction is encountered. B) If when the mass starts from the same height as in part A), the...

A block of mass 11.0 kg slides from rest down a frictionless 33.0° incline and is stopped by a strong spring with k = 2.80 ✕ 104 N/m. The block slides 3.00 m from the point of release to the point where it comes to rest against the spring. When the block comes to rest, how far has the spring been compressed?

a block of mass 10 kg is initially at rest when it slides down a frictionless incline whose height is 10 m and is pitched at an angle of 30 degrees. At the bottom of the incline the mass encounters a horizontal surface that has a coefficient of kinetic friction of 0.4 with the mass. How far from the bottom of the incline will the mass come to a stop?
