Question

8. Jax bounced a dodgeball off a wall. The dodgeball has a momentum of 32.6 kg · m/s after the

Answer 1

Answer:

$32.6\ \text{kg m/s}$

Explanation:

$p_f$ = Final momentum of the system = $32.6\ \text{kg m/s}$

According to the principle of conservation of angular momentum we have

$p_i=p_f\\\Rightarrow p_i=32.6\ \text{kg m/s}$

The wall is not moving so the initial and final momentum of the system are equal.

So, the total momentum of the system before the collision is $32.6\ \text{kg m/s}$.
