Image shows the position-versus-time graphs for two objects, A and B, that are moving along the same axis.a. At the instant t = 1 s, is the speed of A greater than, less than, or equal to the speed of B? Explain.b. Do objects A and B ever have the same speed? If so, at what time or times? Explain.
Please answer letter a,b, and c.
A car travels along a straight road (in the +x direction). When the car changes speed, it does so uniformly. The position of the car as a function of time is shown in the figure below. Hint: By extrapolating the straight sections of the graph, you can estimate the time during which the speed is changing. This, with the change in speed, lets you estimate the magnitude of the acceleration.
Select the appropriate choice for each statement.
Options: {greater than/ less than/ equal to}
1. The magnitude of the acceleration at P is ... that at T.
2. The speed at T is ... that at R.
3. The speed at P is ... that at T.
4. The speed at N is ... that at T.
5. The x-acceleration at R is ... 0.
6. The magnitude of the acceleration at R is ... that at U.
