Q1. A solid disk of radius 6.00 and mass 1.75 that is rolling at a speed of 2.10 begins rolling without slipping up a 10.00 slope.
Q2. A civil engineer wishes to plan a curved exit ramp for a highway in a way that a car will not have to rely on friction to round the curve without skidding. In the other words, a car moving at the designated speed can negotiate the curve even while the road is covered with ice. Such a ramp is usually banked; this means the roadway is tilted toward the inside of curve. Suppose the designated speed for the ramp is to be 13.40 m/s (30.00 mi/h) and the radius of the curve is 50.00 m. At what angle should the curve be banked?
If, on other hand, she first kicks it to player 2, who then kicks it into the net, the ball undergoes two successive displacements, y and x. What are the magnitude and direction of x and y.
A 60-kg basketball is dropped out of a window that is 6.1m above the ground. The ball is caught by a person whose h&s are 1.5m above the ground. Find gravitational potential energy of the ball.
A hollow cylinder of radius and height has a total charge uniformly distributed over its surface. The axis of the cylinder coincides with the z axis, and cylinder is centered at the origin.

A child goes down a playground slide with an acceleration of 1.20 m/s2. Compute the coefficient of kinetic friction between child and slide if the slide is inclined at an angle of 32.2° below the horizontal.
On a cello, the string with the largest linear density (1.54 10-2 kg/m) is C string. This string produces a fundamental frequency of 63.4 Hz and has the length of 0.795 m between the two fixed ends. Find tension in the string.
A 35.0-g bullet moving at 475 m/s strikes a 3.2-kg bag of flour that is on ice, at rest. The bullet passes through the bag, leaving at 225 m/s. How fast is the bag moving while the bullet exits.
What is the time of oscillation of block
