- 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).Initially, ball 1 rests on an incline of height h, and ball 2 rests on an incline of height h/2 as shown in the figure below. They are released from rest simultaneously and collide elastically in the trough of the track. If m2 = 9m1, m1 = 0.043 kg, and h = 0.57 m, what is the velocity of each ball after the collision? (Assume the balls slide but do not roll. Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left. Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) v1f = m/s v2f = m/sInitially, ball 1 rests on an incline of height h, and ball 2 rests on an incline of height h/2 as shown in the figure below. They are released from rest simultaneously and collide elastically in the trough of the track. If m2 = 9m1, m1 = 0.040 kg, and h = 0.35 m, what is the velocity of each ball after the collision?

- Now let's consider the impulse associated with kicking a soccer ball (Figure 1). The ball has mass 0.40 kg . Initially it moves horizontally to the left at 20 m/s, but then it is kicked and given a velocity with magnitude 30 m/s and direction φ=45∘ upward and to the right. Find the impulse of the force and the average force on the ball, assuming a collision time Δt=0.010s a) Suppose the ball is moving at 30 ∘ downward from the horizontal before it is kicked. If all the numerical values are the same as before, find the magnitude of the average force on the ball. b)Find the direction of the average force on the ball found in Part A.If the momentum of a system is conserved, is the momentum of each particle in the system necessarily conserved?
