Consider a ball whose velocity is as follows: 3·cm/s at t=0·s 19·cm/s at t=1·s, 31·cm/s at t=2·s, 39·cm/s at t=3·s, and 43·cm/s at t=4·s. (a) Which of the following statements describes the velocity and acceleration of the ball? Choose one answer only. 1.increasing velocity, increasing acceleration 2.increasing velocity, constant acceleration 3.increasing velocity, decreasing acceleration 4.decreasing velocity, increasing acceleration 5.decreasing velocity, constant acceleration 6.decreasing velocity, decreasing acceleration Wouldn't the answer be #5? (b)In order to move as described in the previous part, the ball could (choose one answer) 1. roll UP a STEEP STRAIGHT SLOPE 2. roll DOWN a STEEP STRAIGHT SLOPE 3.roll UP a CURVED IN SLOPE (similar looking to a valley) 4.roll DOWN a CURVED IN SLOPE 5.roll UP a HILL CURVED OUT 6.roll DOWN a HILL CURVED OUT I was thinking the answer would be between 1 and 2 for (b)....would it be 1 since the velocity speeds up then slows down, almost like it is going up slope?
