In a baseball game, a batter hits the ball at a height of 4.60 ft above the ground so that its angle of projection is 52.0° to the horizontal. The ball lands in the grandstand, 39.0 ft up from the bottom; see Fig. The grandstand seats slope upward at 28.0° with the bottom seats 358 ft from home plate. Calculate the speed with which the ball left the bat. (Ignore air resistance.)

Round of to three significant figures,
v₀ = 115 ft/ s
Therefore, the speed with which the ball leaves the bat is 115 ft/s .

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
