Cart 1 amd 2 are now moving toward each other when they collide and stick together. Cart 1 has a mass of 500g (.5kg) and is travelling at a speed of 0.30m/s to the right. Cart 2 has a mass of 350g (.35kg) and is travelling at a speed of 0.55m/s to the left.
A) What is their velocity (speed and direction) after the collision?
B) What % of the initial KE is lost in the collision?
Please show all work, thank you!
Given mass of cart 1,m1 =0.5kg
initial speed of cart 1,u1 =0.3m/s
mass of cart 1,m2 =0.35kg
initial speed of cart 2 ,u2 =-0.55m/s
-------------------------------
Momentum is conserved
Mometum before collision =momentum after collision
ANSWER: Velocity after collision =0.05m/s towards left
