A person drops a cylindrical steel bar (Y = 1.00 × 1011 Pa) from a height of 1.00 m (distance between the floor and the bottom of the vertically oriented bar). The bar, of length L = 0.51 m, radius R = 0.0075 m, and mass m = 1.00 kg, hits the floor and bounces up, maintaining its vertical orientation. Assuming the collision with the floor is elastic, and that no rotation occurs, what is the maximum compression of the bar?
Two point charges are on the y axis. A 3.80-µC charge is located at y = 1.25 cm, and a -2.18-µC charge is located at y = -1.80 cm. Find the total electric potential at the origin
A 60 kg skier starts from rest at a height of H = 21 m above the end of the ski-jump ramp. As the skier leaves the ramp, his velocity makes an angle of 28° with the horizontal. avoid the effects of air resistance and assume the ramp is frictionles..
