Question

Calculate the force required to impart to car a velocity of 30m/s in 10 seconds from rest. The mass of car is 1500 kg?





​

Answer 1

Answer:

So the difference in these two velocities is 30 – 0 = 30 m/s. Hence, the acceleration of the car is calculated as this difference in velocities / time, means here it is 30 / 10 = 3. The formula for finding the force is acceleration x mass, i.e. 1500 x 3 = 4500 Newton.
