Question

Calculate the force required to impart to a car, a velocity of

30 ms–1 in 10 seconds. The mass of the car is 1,500 kg​

Answer 1

Answer:

means here it is 30 / 10 = 3.

Step-by-step explanation:

When a car starts from the rest, its initial velocity is 0 and here its moving velocity is mentioned to be 30m/s.

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.  

Answer 2

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
