A driver drives a car at uniform velocity along a road. The driver sees a hazard and applies the brakes.What is the car’s motion as it moves through the thinking distance and as it moves through the braking distance?*1 point

he car’s speed changes as it leaves the stop sign.0 m 10 m 20 m 30 m 40 m 50 m 60 m 70 m 80 m 90 m0 s 2 s 4 s 6 s 8 sThe above figure shows that the body(1) covers equal distance in equal interval of time.(2) covers equal displacement in equal interval of time.(3) exhibits non-uniform motion.(4) exhibits uniform motion.

A car is moving on a straight road with uniform acceleration. The following table gives the speed of the car at various instants of time :Speed (m/s) : 5    10     15     20     25     30Time (s)        : 0    10     20    30     40     50The distance travelled by the car in 50 seconds.

A car driving along a road produces the distance-time graph below.Describe the motion of the car at the four marked points, with reference to its acceleration and speed.Write 3-4 sentences in your answer.

A stationary car is stopped at a traffic light. When the light turns green at  , a truck with constant speed passes the car. The car uniformly accelerates to its top speed in   then moves at a constant speed. The truck is represented by the dotted line and the car is represented by the solid line.
