Chapter 2 Problem Set GE 208K 1. The position versus the time for a certain particle moving along the x axis is shown in the figure below. Find the average velocity in the time intervals a. 0 to 2 s b. 0 to 4 s c. 4 to 7 s d. 0 to 8 s 2. A particle moves according to the equations 2 10 t x = where x is in meters and t is in seconds. a. Find the average velocity for the time interval from 2.00 s to 3.00 s b. Find the average velocity for the interval from 2.00 s to 2.10 s 3. Find the instantaneous velocity of the particle described in the figure 1 at the following times: a. t = 1.0 s b. t = 3.5 s c. t = 4.5 s d. t = 7.5 s 4. The position of a particle moving along the x axis varies in time according to the expression 2 3 t x = where x is in meters and t is in seconds. Evaluate its position at a. t = 3.0 s b. at 3.0 s + t c. Evaluate the limit of x/ t as t approaches zero, to find the velocity at t = 3.0s 5. A 50.0g super ball traveling at 25.0 m/s bounces off a brick wall and rebounds at 22.0 m/s. A high speed camera records this event. If the ball is in contact with the
