The engine of a car provides a forward force of 1240 N and the total resistive force on the car is 800N. If the mass of the car is 1220 kg, determine the distance the car has to travel from the rest before acquiring a speed of 4 m s\(^{-1}\).
A small object of mass 50 g is released from a point A. Determine the velocity of the object when it reaches a point B, a vertical distance of 30m below A. [g = 10 ms\(^{-2}\)
In which of the following situations is friction not useful?
Tyres are treaded to?
A car starts from rest and covers a distance of 40 m in 10 s. Calculate the magnitude of its acceleration
