Question

A car is moving along a road. (a) The car has an initial velocity of 26 m/s. The car then accelerates at 1.2 m/s2 until it reaches a velocity of 35 m/s. (i) State the formula linking acceleration, change in velocity and time taken. (ii) Calculate the time taken for the car to accelerate to 35 m/s.​

Answer 1

Answer:

For example, a car accelerates in 5 s from 25 m/s to 3 5m/s. Its velocity changes by 35 - 25 = 10 m/s. Therefore its acceleration is 10 ÷ 5 = 2 m/s2
