Question

Example 5. What is the work to be done to increase the
velocity of a van from 10 m/s to 20 m/s, if the mass of the
is 2000 kg?​

Answer 1

Answer:

the velocity of an object is doubled, then its kinetic energy becomes 4 times the original value, because it is proportional to the square of the velocity. Hence, kinetic energy = 25 × 4 = 100
