A student plays tennis several times a week. She notices that the tennis ball seems to bounce higher on some courts than on other courts. She wonders if this has something to do with the surface of the court. Identify the Independent Variable. *

I need help with the attached question, please show steps.

Write down the expression for period of a pendulum of length I and the gravitational field strength g. Please use square root and power please use sqrt(A*B) and (A*B)^2. Please use the "Display response" button to check you entered the answer you expect. "*" for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "-" signs as appropriate. For T= Display response

A 1.1 N ball is shot horizontally out of a spring gun from a height of 0.9 and lands 2 m horizontally away from the gun. What is the spring constant in N/m of the spring which launched the ball if the ball compressed the spring 0.4 m?

A car with a mass  m = 1000.0kg  is moving on a horizontal surface with a speed  v = 20.0m/s  when it strikes a horizontal coiled spring and is brought to rest when the spring is compressed by a distance  d = 3.0m.  Calculate the spring stiffness constant  k  by...  (a) select appropriate common equations and make appropriate substitutions that are specific to the problem, and algebraically manipulate the equations to end with an algebraic expression for the variable the problem is asking you to solve for. (b) Show the numeric substitution of given quantities and show the final numeric result. (c) Draw a free body diagram for the system and define the given quantities.

1 A hollow steel ball weighing 4 pounds is suspended from a spring. This stretches the spring feet. The ball is started in motion from the equilibrium position with a downward velocity of 4 feet per second. The air resistance (in pounds) of the moving ball numerically equals 4 times its velocity (in feet per second). Let u(t) be the displacement of the mass from equilibrium. Suppose that after t seconds the ball is u feet below its rest position. Find u (in feet) in terms of t. (Note that the positive direction is down.) Take as the gravitational acceleration 32 feet per second per second. u = 4te^(-24t) How would you characterize the damping in this mass-spring system? underdamped
