Question 2 WAEC_MODEL_QUESTIONS_VOL1 • 2022 • PHYSICS • essay

A car moves along a straight road. At time t = 0 s the car is at point O and starts from rest. It accelerates uniformly for 5 s, then travels at a constant speed for 10 s, and finally decelerates uniformly to rest in 4 s.

Question Parts

( a )

During the first 5 s the car covers a distance of 100 m. Determine the magnitude of the constant acceleration in this phase.

( b )

Find the speed of the car at the end of the acceleration phase (i.e., at t = 5 s).

( c )

Calculate the total distance travelled by the car during the whole motion.

( d )

Sketch a velocity–time graph for the whole motion, clearly indicating the three phases, and state the area under the graph.
