An air-track cart with mass m1=0.28kg and initial speed v0=0.80m/s collides with and sticks to a second cart that is at rest initially.
Part A
If the mass of the second cart is m2=0.53kg, how much kinetic energy is lost as a result of the collision?
Express your answer to two significant figures and include appropriate units.
Mass of the first cart = m1 = 0.28 kg
Mass of the second cart = m2 = 0.53 kg
Initial velocity of the first cart = V1 = 0.8 m/s
Initial velocity of the second cart = V2 = 0 m/s (At rest)
Velocity of the carts after the collision = V3
By conservation of linear momentum,
Initial kinetic energy of the system = KE1
Final kinetic energy of the system = KE2
Kinetic energy lost as a result of the collision = KE
A) Kinetic energy lost as a result of the collision = -0.0586 J
