Question

Constant Acceleration Worksheet 1. A ball starts from rest & rolls down an incline for 6 cm in the 1st second. Find: a) The average speed, V, for the first second (Vad/t b) The initial speed, V, If Vav (v vV2, what is vr, the final speed after 1 sec? In the next second from t1s to t 2s, the ball rolls 18 cm. Find c) The average speed, Vav, for the interval from 1-2 seconds (a d/t) d) The initial speed at 1 sec, (V)/2, what is vi, the final speed after 2 sec? e Make a velocity vs time graph, find the acceleration (a Av/At), & Vava for the full 2 sec. 2. A baseball starts from rest and rolls 50.0 m down a hill in 10.0 seconds. (a) What is the average speed (Vav d/t)? (b) What is the initial speed? Since Vava = (Vi + Vr)/2. what is vr, the speed at 10 seconds? c) Make a velocity vs time graph, find the acceleration and average speed for the 10 sec.
