Fuji, in Japan. (a) At what initial speed would a bomb have to be ejected, at angle O 35° to the horizontal, from the vent at A in order to fall at the foot of the volcano at B, at vertical distance h= 3.30 km and horizontal distance d 9.40 km? Ignore, for the mo- ment, the effects of air on the bomb's travel. (b) What would be the time of flight?

A small airplane flying horizontally with a speed of 150 miles/hr at an altitude of 400 feet above aremote valley drops an emergency medical package at A. The package has a parachute whichdeploys at B and allows the package to descend vertically at the constant rate of 6 ft/sec. If the dropis designed so that the package is to reach the ground 37 seconds after release at A, REQUIRED: Determine the horizontal lead L so that the package hits the target. Neglect atmospheric resistance from A to B.

Problem 4: A soccer ball is kicked from ground level across a level soccer field with initial velocity vector vo = 8 m/s at 0= 16° above horizontal. The soccer ball feels wind resistance which causes it to slow horizontally with constant acceleration magnitude a, = 0.54 m/s, while leaving its vertical motion unchanged. Assume any other air resistance is negligible. Choose the positive direction ofx from initial point towards final point of flight. Use a Cartesian coordinate system with the origin at the ball's initial position.
