A boy throws a stone from a truck that moves with 60 km/h. The stone is thrown with 22 m/s with respect to the truck and at an angle of 63" with the horizontal. Assume the stone was 3.5 m from the ground at the moment of the throw. a) Draw a GENERAL diagram with a well defined coordinate system. b) When will the stone hit the ground. c) If the truck starts accelerating at the moment of the throw with constant acceleration of 6.0 m/s at what distance from the truck will the stone hit the ground
