Answer:
The work done by the car is 363 kJ
Explanation:
Work : Work is said to be done when a Force moves an object through a certain distance. Work and Energy are interchangeable because they have the same unit. The unit of work is Joules (J).
Mathematically work done can be expressed as,
E = W = 1/2mv²
W = 1/2mv²................................ Equation 1
Where E = Energy, W = work done, m = mass of the car, v = velocity of the car
Given: m=1500 kg, v=22 m/s
Substituting these values into equation 1
W = 1/2(1500)(22)²
W = 750 × 484
W = 363000 J
W = 363 kJ
Thus the work done by the car is 363 kJ
