Q. A person jumps up and down on a trampoline, while staying in contact with it. The motion is simple harmonic motion and it takes 1.90s to complete one cycle. The height of each bounce above the equilibrium position is 0.45cm. Determine (a) the amplitude and (b)the angular frequency of the motion. (c)What is the highest speed attained by the person?

Runner A is at first 5.4 km west of a flagpole and is running with a constant velocity of 2.6 km/h due east. Runner B is initially 3.0 km east of the flagpole and is running with the constant velocity of 8.8 km/h due west. What would be the distance ..
A spring of constant 3.00 x 10^4 N/m is between a rigid beam and the output piston of a hydraulic lever. An empty container with negligible mass sits on the input piston. The input piston has Areai and output piston has area 18 A.
Nitrogen and oxygen in their liquid states have densities only 0.80 and 0.90 that of water. Atmospheric pressure is due primarily to weight of nitrogen and oxygen gas in the air. If atmosphere liquefied would its depth be greater or less than 10.30 m..
