Question

Question

How much work is required to increase the velocity of a 40 kg mass from 10 m/s to 70 m/s? Give the answer to 1 decimal place.

Answer 1

Answer #1

Initial velocity=V_i =10m/s

Final velocity =V_f=70m/s

Using work energy theorem

Work don=W= change in kinetic energy

W= 96000 J

Answer 2
