Physics

A ball of unknown mass m is tossed straight up with initialspeed v. At the moment it is released, the ball is a height h abovea spring-mounted platform, as shown in the figure below. The ballrises, peaks, and falls back toward the platform, ultimatelycompressing the spring a maximum distance d from its relaxedposition. Assume that the spring is perfectly ideal with springconstant k, and that the mass of the spring and platform isnegligible.

What is the mass m, assuming that there is no friction or airresistance? Using g to represent the acceleration due to gravity,enter an expression for m in terms of g, h, d, k, and v.

Using g to represent the acceleration due to gravity, enter theexpression for m in terms of g, h, d, k, and v.
