1. The problem statement, all variables and given/known data In an experiment, a ball was released from rest at the top of a slope and rolled a distance of 2.0 m down the slope in 8.0 s. Calculate (a) its average speed in this time (b) the speed after 8.0s from rest (c) the acceleration of the ball Basically, I got the answer for a... Which is simply Distance Tot. divided by Time Taken = 2.0 m/8.0 s = 1/4 m/s The answer for b is 0.50 m/s. I have come to a conclusion that the average speed is x0.5 of the speed at that particular instance. (2x Avg. speed in that 8s = Speed of object in 8s) However, I don't get why this came to be. Someone please explain to it to me. Thanks For c... Simple also (after getting b) Which is Velocity/Time 0.50 m/s divided by 8s = 0.0625 m/s 2 Basically, All I need is an explanation for Part b.
