Mathematics (AS & A Level) · May / June 2022 · Paper 41 · Question 5

Two racing cars A and B are at rest alongside each other at a point O on a straight horizontal test track. The mass of A is 1200kg. The engine of A produces a constant driving force of 4500N. When A arrives at a point P its speed is 25ms−1. The distance OP is d m. The work done against the resistance force experienced by A between O and P is 75000J.
