The amount of work required to increase the speed of the car is 275000 J.

To calculate the amount of work required to increase the speed of the car, we use the formula below.

Formula:

  • W = m(v²-u²)/2................ Equation 1

Where:

  • W = amount of work needed to increase the speed of the car
  • m = mass of the car
  • u = initial speed of the car
  • v = final speed of the car.

From the question,

Given:

  • m = 1100 kg
  • u = 20 m/s
  • v = 30 m/s

Substitute these values into equation 1

  • W = 1100(30²-20²)/2
  • W = 1100(900-400)/2
  • W = 1100(500)/2
  • W = 1100×500/2
  • W = 275000 J

Hence, The amount of work required to increase the speed of the car is 275000 J.
