A bow is pulled back a distance X and fires an arrow straight up into the air where it reaches a height H the same arrow is now pulled back 3x in a new bow with a string constant half that of the original bow. If this arrow is short straight up into the air how high will it go?

Aparticle moves according to a law of motion s = f(t), 0 ≤ t ≤ 12, where t is measured in seconds and s in feet. f(t) = cos(πt/6) (a) find the velocity at time t (in ft/s).
