Question

How do I find the answer I’m pretty confused I was out with Covid for 2 weeks for I never got shown this in class this is the homework my teacher gave me

Answer 1

We will determine the final speed as follows:

`v_{\text{f}}=(850m)/(4.22s)\Rightarrow v_f=201.4218009m/s`
`\Rightarrow v_f\approx201m/s`

So, superman's final velocity is approximately 201 m/s.

[In this case superman's initial velocity is a datapoint that is not necessary]
