Consider the situation where a baseball player with mass slides to a stop on level ground. Using energy considerations, calculate the distance the baseball player slides, given that his initial speed is and the force of friction against him is a constant
In the above diagram, the bob of a pendulum with mass is released from height Because of air resistance, the speed of velocity at the lowest position is Find the loss in the total mechanical energy of the bob.
The gravitational acceleration is
A roller-coaster of mass has a speed of as it goes over the top of a -meter-high hill. Then it goes over a another hill of height meters, and at the crest of that hill, the roller-coaster is moving at How much work did friction do on the coaster during its movement between the two hills?
The gravitational acceleration is
A skier with mass coasts up an inclination with angle and height at an initial speed of Find the square of her final speed at the top, given that the coefficient of kinetic friction between her skis and the snow is
The gravitational acceleration is
An object with mass at the top of a tall hill starts to go down from rest. The downhill portion of the run is covered with frictionless material but the flat section at the base of the hill has a spot of friction in length. The object comes straight down the hill, over the spot of friction at the bottom, hits and presses the the damping spring in the process. If the spring constant is what is the magnitude of kinetic friction between the object and flat section.
The gravitational acceleration is and air resistance is negligible.
