Science Question on Newton’s Second Law Of Motion
An automobile vehicle has a mass of 1500 kg. What must be the force between the vehicle and road if the vehicle is to be stopped with a negative acceleration of 1.7 m s–2?
Answer
Mass, m= 1500 kg, Acceleration, a= –1.7 ms-2 From Newton's second law of motion, F = ma = 1500 × (–1.7) = –2550 N
