Question

A car travels a certain distance along a straight road (in the +x direction). The distance the car travels as a function of time is shown in the figure below. When the car changes speed it does so uniformly. Select the appropriate choice for each statement.

1.At 50 sec, the speed is as high as it gets.
2.The acceleration magnitude at 15 sec is ..... the acceleration magnitude at 36 sec.

3. The x-acceleration is ..... zero at 50 sec .
4.The x-acceleration is ..... zero at 15 sec.
5.The speed is ..... zero at 23 sec.
6.The speed at 64 sec is ..... the speed at 50 sec.
