3-) a farm truck moves due east with a constant velocity of 9.50 m/s on a limitless, horizontal stretch of
road. a boy riding on the back of the truck throws a can of soda upward (fig. p4.54) and catches the
projectile at the same location on the truck bed, but 16.0 m farther down the road.
(a) in the frame of reference of the truck, at what angle does the boy throw the can? .
(b) what is the initial speed of the can relative to the truck?
