Describe the movement of the car in terms of speed.
Answer
MEDIUM
The motion of a train is depicted in the following velocity-time graph.
a) Determine the acceleration between O and P.
b) Determine the acceleration between P and Q.
c) What is the total distance travelled by the train from O to R?
d) Calculate the average speed of the train.
Answer
HARD
A car accelerates to a velocity of 20 m/s in 10 s from rest. It then continues with this constant speed for 20s before decelerating to a stop in t s.
a) Sketch the speed-time graph for the motion.
b) If the car has a deceleration of 5 m/s2, determine t.
c) Calculate the average speed of the motion.
