Question

A 0.50-kg red cart is moving rightward with a speed of 60.0 cm/s when it collides with a 1.50-kg blue cart that is moving leftward with a speed of 12.0 cm/s. After the collision, the two carts stick together and move to the right with a speed of 6.0 cm/s.

What is the before collision of the red cart, blue cart and system

What is the after collision of the red cart, blue cart and system

What is the momentum change of the red cart, blue cart and system

Answer 1

Step-by-step explanation:

Before the collision:

p = m₁v₁ + m₂v₂

p = (0.50 kg) (0.60 m/s) + (1.50 kg) (-0.12 m/s)

p = 0.12 kg m/s

After the collision:

p = (m₁ + m₂) v

p = (0.50 kg + 1.50 kg) (0.06 m/s)

p = 0.12 kg m/s

The change in momentum is 0 kg m/s.
