Question

Which has more momentum, a 1000 kg car moving 1 m/s or a 70 kg person sprinting at 8 m/s?

Answer 1

p = mv  

p = 1000 kg x 1 m/s = 1000 kgm/s  

p = 70kg x 8 m/s = 560 kgm/s  

1000 kg car moving at 1 m/s has more momentum.

Answer 2

A 1000 kg car moving 1 m/s have more momentum which is 1000 kg meters per second.

We have to determine which has more momentum, a 1000 kg car moving 1 m/s or a 70 kg person sprinting at 8 m/s?

According to the question

The momentum for the given condition can be calculated following formula;

$\rm Momentum= {Mass \times Velocity}$

The momentum for  a 1000 kg car moving 1 m/s is,

$\rm Momentum= Mass \times Velocity}\\\\\rm Momentum= 1000 \times 1}\\\\ \rm Momentum= 1000$

The momentum is 1000 kg meters per second.

And the momentum for a 70 kg person sprinting at 8 m/s is,

$\rm Momentum= Mass \times Velocity}\\\\\rm Momentum= 70 \times }{8}\\\\ \rm Momentum= 560$

The momentum is 560 kg meters per second.
