Ex 2. A 50kg mass initially at rest
explodes into two fragments. The 30kg
fragment moves west at 40m/s. What is
the velocity of the 20kg fragment?

The velocity of the second fragment is 60 m/s.

What is velocity?

Velocity can be defined as the rate of change of displacement of a body.

To calculate the velocity of the second fragment we use the formula below.

Formula:

  • MV = mv................ Equation 1

Where:

  • M = mass of the first fragment
  • V = Velocity of the first fragment
  • m = mass of the second fragment
  • v = velocity of the second fragment

Make v the subject of the equation

  • v = MV/m............. Equation 2

From the question,

Given:

  • M = 30 kg
  • V = 40 m/s west.
  • m = 20 kg

Substitute these values into equation 2

  • v = (30×40)/20
  • v = 60 m/s.

Hence, the velocity of the second fragment is 60 m/s.
