- Solve step by stepA ball is launched upward from the ground at an initial vertical speed of v0 and begins bouncing vertically. Every time it rebounds, it loses a proportion of the magnitude of its velocity due to the inelastic nature of the collision, such that if the speed just before hitting the ground on a bounce is v, then the speed just after the bounce is rv, where r < 1 is a constant. Calculate the total length of time that the ball remains bouncing, assuming that any time associated with the actual contact of the ball with the ground is negligible.Suppose you use an ideal pulley of the type shown in image (a) in the figure below to support a car engine of mass 145 kg.

The banner is hanging from a bar of length L that is supported by a cable attached a distance L/2 above the end of the bar. There are two options, attach the cable to the end of the bar (blue cable) or at a point somewhere nearer the middle of the bar (red cable). Let Fend be the tension if a cable is attached to the end of the bar and Fmid be the tension if a cable is attached closer to the middle of the bar. (There is only one cable at a time.) Let the mass of the sign be 6.07 kg and the mass of the bar be 4.02 kg. Let the red cable be attached a distance 0.60 L from the right end of the bar. What is the ratio of the forces, Fmid/Fend? Give your answer to three significant digits to avoid being counted off due to rounding. As this is a ratio, there are no units. L ලා L/2A steel cable with mass is lifting a girder.
