Q. A runner moving at a constant speed of 11.7 m/s rounds a curve of radius 4.10 m. Compute the acceleration of the runner. (State the magnitude of this acceleration.)
Q. A projectile that is fired from a gun has an initial velocity of 93.0 km/h at an angle of 64.0° above the horizontal. When the projectile is at the top of its trajectory, an internal explosion causes it to separate into two fragments of equal mass. One of the fragments falls straight downward as though it had been released from rest. How far from the gun does the other fragment land?
