Problem 3 Free-Body Diagrams Draw a free-body diagram for the object described in the following scenarios. Make the length of the vector arrows approximately to scale. In addition, include an additional vector denoting the direction of acceleration. (a) An elevator, suspended by a cable, is speeding up as it descends towards the ground. (b) A rocket is moving at constant speed upwards. Do not ignore air resistance. (c) A box is sitting in the back of a moving truck when the truck slams on its brakes. The box does not move in the bed of the truck. (d) A soccer ball being kicked by you. Your foot and the ground are still in contact with the ball. (e) The soccer ball of the previous part is now in the air, do not ignore air resistance.
