Question

In 1996, Michael Johnson ran 10.4 m/s. Johnson's mass at the time of his record-breaking run was about 77 kg. What was his momentum at this speed?

Answer 1

`\huge\boxed{\sf P = 800.8\ Ns}`

Step-by-step explanation:

Given data:

Speed = v = 10.4 m/s

Mass = m = 77 kg

Required:

Momentum = P = ?

Formula:

P = mv

Solution:

Put the given data in the above formula.

P = (77)(10.4)

P = 800.8 Ns
