Initially, a particle is moving at 5.45 m/s at an angle of 38.5 above the horizontal. Four seconds later, its velocity is 6.24 m/s at an angle of 54.3 below the horizontal. What was the particle's average acceleration during these 4.00 seconds in the x-direction (enter first) and the y-direction?
Two friends, Barbara and Neil, are out rollerblading. With respect to the ground, Barbara is skating due south at a speed of 2.5 m/s. Neil is in front of her. With respect to the ground, Neil is skating due west at a speed of 2.1 m/s. Find Neil's velocity (a) magnitude and (b) direction relative to due west, as seen by Barbara.
A rugby player runs with the ball directly toward his opponent’s goal, along the positive direction of an x axis. He can legally pass the ball to a teammate as long as the ball’s velocity relative to the field does not have a positive x component. Suppose the player runs at speed 4.0 m/s relative to the field while he passes the ball with velocity relative to himself. If has magnitude 6.0 m/s, what is the smallest angle it can have for the pass to be legal?
