A student standing on a stationary skateboard tosses a textbook, mt = 1.05 kg, to a friend standing in front of him. The student and the skateboard have a combined mass of mc = 104 kg and the book leaves his hand at a velocity of 2.25 m/s at and angle of 22 degrees with respect to the horizontal.

Randomized Variables

mt = 1.05 kg

mc = 104 kg

Vb = 2.25 m/s

θ = 22 degrees.

what is an expression for the magnitude of the velocity the student has, Vs, after throwing the book?

2. Relevant equations

3. The attempt at a solution

I thought that the momentum would be equal and opposite, so I set:

mt(vb)=mc(v)

solved for v, and got .023

I feel as if I am working this terribly wrong.
