Compute all parts of given problem:
Problem: A 28 kg block slides down a ramp which is inclined at an angle of 20 degrees up from the horizontal. The block and the ramp have a co-efficient of kinetic friction of 0.22. The top of the ramp is 2.5m above the ground.
Part A: How much energy was lost to friction as the block slid down the ramp?
Part B: What is the final speed of the block when it reaches the bottom of the ramp?
Please, show work so I can understand the concept. Thanks.
Recent studies have raised concern about `heading' in youth soccer(i.e., hitting the ball with the head). A soccer player `heads' asize 3 ball deflecting it by 59.0°, and keeps its speed of11.60 m/s constant.
Bobby has a simple pendulum system with a ball of mass M at the end of a string of length L. He also has a similar system consisting of a uniform rod of mass M and length L.

The coefficient of static friction between the block and table's surface is &mu s = 1/3. The mass of the block that is hanging down is n1 Kg. The tangent of the angle shown in the figure is tan & theta = n2. What is the minimum value of mass, n3 Kg t..
A moon orbits a planet because of the gravitational force between them. Similarly, each body also experiences a tidal force due to gravity. Consider how the magnitude of the tidal force changes as distance between a planet and moon varies.
consider light that is refraced by a prism shaped like an equilateral triangle. the incident ray is parallel with the
In this section assume the sound speed in air is 343 m/s . A goose flying toward you at 11.3 m/s emits a squawk, which you hear at 246 Hz . Find the wavelength of the sound you hear
