vehicle of mass 1000 kg has a kinetic energy of 20,000 joules at an instant the velocity at that instant is
Answers
velocity of vehicle at that instant is 6.32 m/s.
it is given that vehicle of mass , M = 1000 kg has a kinetic energy of K.E = 20000 J at an instant.
we have to find the velocity of vehicle at that instant.
we know, kinetic energy, K.E = 1/2 mv²
⇒ 20000 = 1/2 × 1000 × v²
⇒ 40000 = 1000 v²
⇒v² = 40
⇒v = √40 m/s
⇒v = 6.32 m/s
therefore, velocity of vehicle at that instant is 6.32 m/s.
