pls see attached file for the question.

so W = change in T + change in V

T = 1/2 mv

for V

and for Vg = mgh, is it mg (1.458)?

im so sorry, i just have no idea about this one.

so W = change in T + change in V

_{e}+ change in_{g}T = 1/2 mv

^{2}+ 1/2 I (w1^2 - w2^2), but how do u find the velocity, shouldn't it be 0 since it starts/stops at v=0.for V

_{e}= 1/2 kx^{2}, how do u know how far it stretches once the moment is applied? :O :(and for Vg = mgh, is it mg (1.458)?
