Question

A 0.097 kg cup falls from the kitchen shelf and shatters on the ceramic tile floor. Assume that the maximum kinetic energy obtained by the cup is 2.6 J and that air resistance is negligible. Calculate the cup's maximum speed

Answer 1

(1/2)*M(Vmax)^2 = 2.6 joules

Solve for Vmax, in m/s

Answer 2

Ek= 1/2mV^
2.6J= 1/2(0.097)v^
2(2.6)/0.097= v^
53.7=V^
V=7.3m/s
