Stationary skateboarder A with a mass of 50 kg pushes stationary skateboarder B with a mass of 75 kg. After the push, skateboarder B moves with a velocity of 2 m s–1 to the right. The velocity of skateboarder A is:

• 3 m s–1 to the left.

• 2 m s–1 to the left.

• 1 m s–1 to the right.

• 3 m s–1 to the right.
