Homework Statement
A 4kg traveling at 14m/s collides with a stationary 8kg cart. The collision causes the 4kg cart to completely stop, and sets the 8kg cart in motion. Determine the velocity of the 8kg cart after the collision.
Homework Equations
m1 = -m2
VFinal-VInitial = m
The Attempt at a Solution
Initially the velocity of the 4kg is 4kg*14m\s, or 56kgm/s.
After it halts completely, therefore a velocity of 0.
m1 = 0-56kgm\s.
Next the 8kg cart; initially it is at 0kg\s.
After it is 8kg*x.
(8x-0) = m2
Thus -56kgm\s = 8x;
x = -7kg/s.
m1 = -m2, therefore -7 becomes 7?
I'm not sure if this is correct. Any help, tips, and resources appreciated.
