Question

What is the work to be done
to increase the velocity of a car from
30 km h- to 60 km h' if the mass of
the car is 1500 kg?​

Answer 1

work done = change in kinetic energy

= 1/2 M [ V^2 - v^2]

= 1/2*1500*2700

= 2025000 J

hope it is helpful.......

Answer 2

Step-by-step explanation:

$\frac{1}{2} m(v {}^{2} - v {}^{2} ) \\ \frac{1}{2} 1500(60 - 30) \\ \\ \\750 \times 30$

$22500$
