Question

If a blue whale has a mass of 1,559.5 kg and a momentum of 16,858.2 what is the magnitude of its velocity

Answer 1

Answer:

Magnitude of velocity = 10.81 m/s

Explanation:

Given

mass of whale, m = 1559.5 kg

Momentum, p = 16858.2 kg.m/s

To find: velocity (v)

We know that momentum is given by equation:

p = mv

v = p/m

  = $\frac{16858.2 kg.m/s}{1559.5 kg}$

  =  10.81 m/s

Hence magnitude of velocity = 10.81 m/s
