When considering a system, how do we know momentum is conserved?

• The mass of the system remains constant during the interaction

• The momentum of the system is greater before the interaction

• The momentum of the system is less before the interaction

• The mass of the system redistributes unequally during the interaction

What is the difference in momentum between a semi-truck and a bicycle both traveling at 5 m/s?

• The bicycle has less momentum because it has a greater mass which increases momentum

• The semi-truck has less momentum because it has a greater mass which decreases momentum

• The semi-truck has greater momentum because it has a greater mass which increases momentum

• The bicycle has greater momentum because it has a greater mass which increases momentum

Which of the following statements about mass, velocity, and momentum of the balls in a Newton’s Cradle is correct?

• The initial weight of the ball is transferred equally to the secondary ball so that initial and final conditions are the same

• The initial momentum of the ball is transferred unequally to the secondary ball so that initial and final conditions are different

• The initial mass of the ball is transferred equally to the secondary ball so that initial and final conditions are the same

• The initial momentum of the ball is transferred equally to the secondary ball so that initial and final conditions are the same

How would you best define the initial conditions of the wheel?

• The wheel has a constant mass of 22 kg with an initial velocity of 5 m/s

• The wheel has a constant mass of 1500 kg with an initial velocity of 5 m/s

• The wheel has a constant mass of 22 kg, with an Initial velocity of 0 m/s

• The wheel has a constant mass of 1500 kg with an initial velocity of 4.5 m/s

How would you calculate the final momentum for the car AFTER it bumps the wheel?

• p=(22)*(4.5)=99 kg*m/s

• p=(1500)*(4.5)= 6,750 kg*m/s

• p=(1500)*(5)=7,500 kg*m/s

• p=(22)*(5)=110 kg*m/s
