1. In a physics lab, you attach a 0.200 kg air-track glider to the end of an ideal spring of negligible mass and start it oscillating. The elapsed time from when the glider first moves through the equilibrium point to the second time it moves through that point is 2.60 s.a) Find the spring's force constant
2. A 42.5 kg chair is attached to a spring and allowed to oscillate. When the chair is empty the chair takes 1.30 s to make one complete vibration. But with a person sitting in it, with her feet off the floor, the chair now takes 2.54 s for one cycle. what is the mass of the person?
3. A tuning fork labeled 392 Hz has the tip of each of the two prongs vibrating with amplitude of 0.600 mm.
a) What is the maximum speed of the tip of a prong?
b) A housefly with mass 0.0270 g is holding on to the tip of one of the prongs. As the prong vibrates, what is the fly's maximum kinetic energy? Assume the fly's mass has a negligible effect on the frequency of oscillation.
two thin rods of length l lie along the x-axis one between xa2 and xa2l and the other between x - a2 and x - a2 - l.

A 66-kg skier starts from rest at the top of a 1200-m-long trail which drops a total of 260m from top to bottom. How much energy is dissipated by friction
A tennis player hits a ball at ground level, giving it an initial velocity of 26.0 m/s at 54.0 degree above the horizontal. Find what is the ball's acceleration at its highest point
The gas in an air cannon expands , from V1= 2.0-m3 to V2= 8.0-m3, while the pressure changes from P1= 6.0-atm to P1= 2.0-atm. If the heat supplied to the gas is 1.2 106-J and 1-atm = 1.013 105-N/m2, what is the change in the internal energy of the ga..
An electron is a subatomic particle (m = 9.11 x 10-31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +8.11 x 105 m/s to a final velocity of 1.21 x 106 m/s while traveling a di..
