Question

What speed would a 0.4 kg football have to be thrown to have a momentum of 8 kg * m/s?

Answer 1

Step-by-step explanation:

p = m * v

where m is the mass of the object and v is its velocity/speed.

In this case, we are given the momentum (p) and the mass (m) of the football. We can rearrange the formula to solve for v:

v = p / m

Substituting the given values, we get:

v = 8 kg * m/s / 0.4 kg

v = 20 m/s
