A basketball player makes a jump shot. The 0.550 kilogram ball is released at a height of 2.10 meter above the floor with a speed of 7.00 m/s. The ball goes through the net 3.10 meter above the floor at a speed of 4.20 m/s. Determine the work done on the ball by air resistance, a non conservative force? J
if you weigh 637N on earth's surface, how much would you weigh on the planet Mars? (Mars has a mass of 6.37x10^23 kg and a radius of 3.43x10^6 m)
A tuning fork vibrating at 666 Hz falls from rest and accelerates at 9.8 m/s 2. How far below point of release is the tuning fork when waves of frequency 626.4 Hz reach the release point? The speed of sound in air is 339 m/s.
Consider a charged metallic spherical shell of radius a=1.75 cm.The potential at a distance of r=6.0 cm from the center of theshell is measured to be 1.5kV. What is the charge on theshell? Calculate the potential on the surface of theshell.
