Homework 2 Due January 23 2007 1. The figure below is a graph of v vs t for a particle moving along a straight line. The position of the particle at t = 0 s is x = 5 m. a) Find the position of the particle at t = 1s and at t = 5 s. b) Sketch the acceleration a versus t . 2. Ball A is dropped from the top of a building of height h at the same instant that ball B is thrown vertically upward from the ground. When the balls collide, they are moving in opposite directions , and the speed of A is three times the speed of B. How far above the ground does the collision occur?

Homework 2 Due January 23 2007 3. A projectile is fired into the air from the top of a 200-m cliff above a flat valley (see figure). Its initial velocity is 60 m/s at 60 ° with the horizontal. Neglecting air resistance, determine distance d (or how far from the base of the cliff does the projectile land). 4. Initially, a particle is moving due west with a speed of 40 m/s, and 5 s later it is moving north with a speed of 30 m/s.
