Answer

Explanation:

Step1: Recall momentum formula

The formula for momentum is $p = mv$, where $p$ is momentum, $m$ is mass and $v$ is velocity. Initially, $p_1=mv_1 = 20000$ kg·m/s.

Step2: Analyze when velocity doubles

When the velocity doubles, $v_2 = 2v_1$. The new momentum $p_2=m\times v_2=m\times(2v_1)=2\times(mv_1)$.

Step3: Substitute initial - momentum value

Since $mv_1 = p_1 = 20000$ kg·m/s, then $p_2=2\times20000$ kg·m/s = 40000 kg·m/s.

Answer:

C. 40,000 kg·m/s
