Homework Statement
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?
Homework Equations
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.
