How much energy is gained by a box of mass when a man.
(ii) runs carrying the box with a speed of to catch the bus?
Step 1: Given data:
Mass
Velocity
Step 2: Find the energy gained by a box:
The energy gained by a box is equal to the kinetic energy of man.
, where is kinetic energy, is mass and is velocity.
Hence, the energy gained by a box of mass 20kg runs carrying the box with a speed of to catch the bus is
