Question 2 NECO • 2025 • PHYSICS • essay

A car moves along a straight road. It starts from rest and accelerates uniformly to a speed of 20 m s⁻¹ in 5 s. It then travels at this constant speed for 40 s, after which it decelerates uniformly to rest in 8 s. During the constant‑speed phase a steady wind exerts a force of 150 N opposite to the direction of motion. The mass of the car is 1200 kg.

( a )

Determine the magnitude of the acceleration during the first phase and the magnitude of the deceleration during the third phase.

( b )

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

( c )

Sketch a velocity‑time graph for the motion and state the gradient of each segment and the area under the graph.

( d )

If the wind force of 150 N acts only during the constant‑speed phase, determine the power output of the engine during that phase.
