- 2. A 400.0 g cart moving at 0.360 m/s has how much momentum? (careful...units!) 3. If the cart in question 2 was to bounce back and return with a velocity of -0.240 m/s , what is its change in momentum (remember that momentum is a vector quantity)? This change in momentum is called the impulse.Two football players collide with a total momentum of 520 kg⋅m/s before the collision. After the collision, Player X has a momentum of 270 kg⋅m/s. What is the momentum for Player Y after the collision? What is their total momentum after the collision? Make sure to show all your work and include proper units.Answer the following questions: 1. A 32 kg child sits at one end of a 3.8 m long seesawWhere should her 72 kg father sit so the center of mass will be at the center of the seesaw? 2. A firework explodes into three pieces as shown in the diagram below. Now that you have set up the equation for the x and y components of the final momentum of the firework, let's do some physics! Given: ∙∙ The initial firework had a mass of 9.0 kg and was launched at vi = 50 m/s vertically straight up. ∙∙ The firework explodes into three pieces of equal mass 3.0 kg. The angles θ1 = θ3 = 40 ∘. ∙∙ Speed v1 = 100 m/s. What is the speed v2? Note: the angles shown for mass m1 and mass m3 are relative to the horizontal x-axis. Mass m2 is moving straight up (y-axis).
