Chapter 4, Problem 35AP
Why is the following situation impassible? A normally proportioned adult walks briskly along a straight line in the +x direction, standing straight up and holding his right arm vertical and next to his body so that the arm does not swing. His right hand holds a ball at his side a distance h above the floor. When the ball passes above a point marked as x = 0 on the horizontal floor, he opens his fingers to release the ball from rest relative to his hand. The ball strikes the ground for the first time at position x = 7.00h.

For a forensics experiment, a student decides to measure the muzzle velocity of the
pellets from his BB gun. She points the gun horizontally. On a vertical wall a
distance 47.3 m away from the gun, a target is placed. The shots hit the target a
vertical distance 0.10 m below the gun's barrel. What is the initial speed of the
pellets?

Answer
The velocity of a particle moving in thex-y plane is given by (4.03i + 7.36j) m/s at time t = 3.64 s. Its average acceleration during the
next 0.020 s is (2.2i + 2.6j) m/s?. Determine the velocity v of the particle at t = 3.660 s and the angle e between the average-
acceleration vector and the velocity vector at t = 3.660 s.
