Problem 2.12

Figure E2.12 shows the velocity of a solar-powered car as a function of time. The driver accelerates from a stop sign, cruises for 20 s at a constant speed of 60 km/h, and then brakes to come to a stop 40 s after leaving the stop sign. (a) Compute the average acceleration during these time intervals: (i) t = 0 to t = 10 s; (ii) t = 30 s to t = 40 s; (iii) t = 10 s to t = 30 s; (iv) t = 0 to t = 40 s. (b) What is the instantaneous acceleration at t = 20 s and at t = 35 s?

Introduction In this lab we studied two­dimensional motion. The purpose is to find horizontal and vertical acceleration and velocity of a ball moving in a plane. We fired a ball out of a Projectile Launcher on to a Pasco timer plate and calculated data. Procedure First, we predicted the horizontal and vertical accelerations of the shadows after the ball leaves the thrower’s hand. To test...
