The amount of energy consumed by a boy in pushing a 60- kg wooden crate was 90 joules. at what velocity did the object move?​

Calculating velocity with energy.

Given

  • Kinetic Energy (KE) = 90 J
  • Mass (m) = 60 kg
  • Velocity (v) = ?

v² = KE / 1/2m

v² = 90 / (1/2)(60)

v² = 90 / 30

v² = 3

√v² = √3

v = √3 m/s
