A ball is released from rest at t= 0.3 s on an inclined segment of track. The ball rolls down the incline onto a 2 m section of level track and then continues down a second incline, which is inclined at the same angle as the first section of track (and therefore causes the same acceleration). The diagram below indicates the location of the ball at several instants in time. Starts from rest t=0.3 s t=2.3 s 2 m t=2,7 s a) What is the speed of the ball on the level segment of track? b) Determine the numerical value of the acceleration of the ball on the first inclined segment of track, being sure to include a description of the direction of the acceleration. c) Determine the final speed of the ball at time = 3.1s. (Hint: Find out how much the speed increases in the given time.) t=3.1 s
