Question

A 48.3 kg student runs down the sidewalk and
jumps with a horizontal speed of 4.34 m/s
onto a stationary skateboard. The student
and skateboard move down the sidewalk with
a speed of 4.07 m/s.

a) Find the mass of the skateboard.
Answer in units of kg.

I got 3.204177 kg

b) How fast would the student have to jump
to have a final speed of 5.27 m/s?
Answer in units of m/s.

I'm getting 5.6196 m/s, but my online homework is prompting me with an incorrect guess.

My work is shown in the picture.
