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.
Choices: True, False, Greater than, Less than, Equal to.
- The speed is ..... zero at 26 sec.
- The x-acceleration is ..... zero at 52 sec .
- At 50 sec, the speed is as high as it gets.
- The speed at 50 sec is ..... the speed at 76 sec.
- The acceleration magnitude at 36 sec is ..... the acceleration magnitude at 15 sec.
- The x-acceleration is ..... zero at 36 sec.
