A car travels for 10s at a steady speed of 20m/s along a straight road. the traffic lights ahead change to red and the car slows down with a constant deceleration so that it halts after a further 8s. a. draw a a speed-time graph to represent the car's motion during the 18 seconds described.
b. use the graph to deduce the car's celebration as it slows down.
c. use the graph to deduce how far the car travels during the 18s described.

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
