Q. After a 0.380-kg rubber ball is dropped from a height of 1.90 m, it bounces off a concrete floor and rebounds to a height of 1.45 m
(a) Determine the magnitude and direction of impulse delivered to the ball by the floor.
(b) Estimate the time the ball is in contact with the floor to be 0.060 seconds. Determine the average force the floor exerts on the ball.
A loudspeaker of mass 25 {rm kg} is suspended a distance of h = 1.60 {rm m} below the ceiling by two cables that make equivalent angles with the ceiling. Each cable has a length of l = 3.50 {rm m}.
Find out the velocity with which he strikes the water. (Hint: When the diver reaches the water, his displacement is y = -3 m (measured from the board), assuming that the downward direction is chosen as the negative direction.)
