1. The sledder shown in (Figure 1) starts from the top of a frictionless hill and slides down into the valley. Suppose that h1 = 4.3 m and h2 = 5.5 m. What initial speed vi does the sledder need to just make it over the next hill? 2. A 42 g ball of clay traveling at speed 6.1 m/s hits and sticks to a 1.0 kg block sitting at rest on a frictionless surface. What is the speed of...

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.

A 4.5 kg box slides down a 4.2-m -high frictionless hill, starting from rest, across a 2.2-m -wide horizontal surface, then hits a horizontal spring with spring constant 550 N/m . The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 2.2-m-long horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.22. Part C How far is the spring compressed? Express your answer...

when it strikes the ground Free-Body Diagram: A pulley system slides down a hill. The hill is tilted up a' an angle O above the horizontal ground, (a) Draw·free-kdy rest if the blocks m and m remain stationary relative to the sliding mass M pulley system. All surfaces are frictionless ulley is massless and frictionless. Mass m is in contact with mass M w the position vs. time graph(s) for all moving masses.

Block A begins at the top of the track with an initial speed. It then slides on the track without friction going down to the bottom and back up to the second platform. Finally, it collides with a stationary block, B and the two stick together and continue to slide. Block A, with mass, mA= 0.75 kg is given an initial velocity, v0= 1.3 m/s. Block A slides without friction along a track downward from a platform at height h1=...

A 150g ball slides down a perfectly smooth incline starting at a height of 2.44m, at rest. At the bottom of the incline is strikes and sticks to a 280g block. The block/ball combo are then free to move along a frictionless rollercoaster track. The first hill is only 23 cm high. Can it make it over this first hill? Defend your response with detailed analysis. If the combo CAN make it over the hill, how fast is it moving...

A 2.00 kg box slides down a rough incline plane from a height h of 1.03 m. The box had a speed of 2.33 m/s at the top and a speed of 1.90 m/s at the bottom. Calculate the mechanical energy lost due to friction (as heat, etc.).

A 5.0 kg box slides down a 5.0-m-high frictionless hill, starting from rest, across a 2.0-m-wide horizontal surface, then hits a horizontal spring with spring constant 500 N/m. The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 2.0-m-wide horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.25. (a) What is the speed of the box just before reaching the rough surface?...

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...
