4. Draw both a position-versus-time graph and a velocity-versus-time graph for an object at rest at x=1m. 5. The figure shows the position-versus-time graphs for two objects, A and B, that are moving along the same axis. At the instant t1 s, is the speed of A greater than, less than, or equa 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. 6. Below...

3. I am driving at 20.0 m/s when (at time t 0 a car pulls out onto the road, 50.0 meters ahead of me. I immediately start to brake, slowing down at 3.0 m/s. Meanwhile the other car, which started at rest, accelerates at 2.0 m/s At-4.0 s, I have slowed down to 8.0 m/s and the other car has sped up to 8.0 m/s; in those first four seconds I have moved 56.0 m and the other car has...
