Homework Statement
A 55kg student stands on a 4.6 kg surfboard moving at 2.0 m/s [E]. The student then walks with a velocity of 1.9 m/s[E] relative to the surfboard. Determine the resultant velocity of the surfboard, relative to the water. Neglect Friction.
Answer: 0.25 m/s[E]
Homework Equations
Conservation of momentum (P = P')
The Attempt at a Solution
I plugged in the values given (relative to the water) into the equation, but I'm not getting the right answer ?
ms = mass of student
mb = mass of board
vs = 2.0m/s
vb = 2.0m/s
vs' = 1.9m/s + 2.0m/s
vb' = ?
