A sledder, starting from top of a hill, sliding down on a frictionless surface. He then reaches a flat surface where his sled experiences friction until it comes to stop, as shown here Energy8.jpg. The sled makes 55-m skid mark on the flat surface. If the coefficient of kinetic friction of the flat surface is 0.2, from what height did the sledder start his journey?

A
4.00 kg block starts sliding from rest from the top of a
frictionless incline, the mass slides along a horizontal surface
and collides with a spring compressing it a distance x. The spring
will compress 3 meters with an applied force of 300N.
A) Calulate the speed of the block at the halfway down the
incline.
B) Calculate the speed of the block at the bottom of the
incline
C) How much work is done on the block by...

3. The cart in the diagram starts from the top of a large hill, rolls down and continues to move along the horizontal track to collide the spring (k 1000 N/m). The spring is attached to a barrier that cannot move. Spring rm The cart collides with the spring and compresses it a distance of 0.50 m. What is the speed of the cart before the collision? (2) a. O(Lo b. What is the maximum speed of the cart at...

A skier starts at the top of a hill with height H, skies down and then climbs a smaller hill. The smaller hill is shaped like a large snowball with a radius R. As the skier skies straight down the side, at what point does she lose contact with the snowball and fly off at a tangent: at what angle α does a radial line from the center of the snowball to the skier make with the vertical? Ignore friction....
