Conservation of Momentum Quiz

What is the initial velocity of the first footballer?

• 5 meters per second

• 6 meters per second

• 4 meters per second

• 7 meters per second

Which formula represents the conservation of momentum?

• m1v1 + m2v2 = m1u1 + m2u2

• m1u1 + m2u2 = m1v1 + m2v2

• m1 + m2 = v1 + v2

• m1u1 - m2u2 = m1v1 - m2v2

What is the combined mass of the two footballers after they collide?

• 180 kg

• 170 kg

• 160 kg

• 150 kg

What is the combined velocity of the footballers after the collision?

• 2.0 meters per second

• 1.5 meters per second

• 1.0 meters per second

• 1.3 meters per second

Why is it important to consider the direction in momentum calculations?

• Because momentum is a scalar quantity

• Because direction affects the magnitude

• Because momentum is a vector quantity

• Because direction is irrelevant
