a) d = 1/2(a x t^2); rewrite to solve for t:
t = sqrt(2 x d / a) = sqrt( 2 x 350 / 9.8) = 8.45 seconds
b) horiz distance = v x t = 60 x 8.45 = 507 meters
c) bombs horizontal component of velocity doesn't change, neglecting air resistance = 60.0 m/s.
d) the helicopter is directly over the bomb if no air resistance
A military helicopter on a training mission is flying horizontally at a speed of 60.0 m/s and accidentally drops a bomb (fortunately not armed) at an elevation of 350 m. You can ignore air resistance.
Find the horizontal and vertical components of its velocity just before it strikes the earth.
