Homework Statement
An arrow of mass 100 g is fired with an initial horizontal velocity of 40 m s–1 to the right at an apple of mass 80 g that is initially at rest on a horizontal surface. When the arrow strikes the apple, the two objects stick together. What is the common velocity of the arrow and apple after the impact?
Homework Equations
Momentum = mass * velocity
The Attempt at a Solution
Initial Momentum of the Arrow
p=m*v
=(.1)(40)
= 4
4=.08* v
therefore v= 50 m/s
the answer says it's 22m/s
