1. Q3 A-car starts accelerating with +5m/s^2 from still (i. e. v=0) when B-car moving with 10m/s is 10m behind. Is the B-car able to catch A- car ? a)yes; b) no.

2. Kinematics General relations between velocity and acceleration

3. Velocity versus time. Calculate the average and instantaneous acceleration from such a graph.

4. Q1. Velocity and acceleration 1.If one is positive the other one has to be positive. 2.If one is equal zero at some time t, the other has to be zero. 3.Their signs are independent. 4.Acceleration is always smaller then velocity.
