Two toy cars have the masses and velocities shown in the diagram below. Before the collision V=4 m/s V 5 m/s+ 4 kg 2 kg After the V 0.5 m/s V-? collision 4 kg 2 kg A) Calculate the momentum of the center of mass (potal) of the car-car system P+oral= m V B) Calculate the impulse of the 4 kg car. C) Calculate the final velocity of the 2 kg car. D) The cars collided for a time of 0.5 seconds. How much force did the 4kg car exert on the 2kg car?

From the figure below Inelastic collisions. The net momentum of the trucks before and after collision is the same, explain?

A 156-gram baseball is hit toward the left by a bat. The magnitude of the force the bat exerts on the ball as a function of time is shown in (Figure 1). -magnitude of impulse = 12 N*s -Magnitude of the ball's velocity when it is at rest = 77 m/s a)what is the magnitude of the ball's velocity after it is hit if it is initially moving to the right at 31 m/s  b)what is the direction of this velocity?

I need to calculate initial and final momentum for 2 runs and then the change in momentum.  the mass of the object is .3 kg  initial velocity of run 1 is -.5 m/s and final velocity is .13 m/s initial velocity of run 2 is -.4 m/s and final velocity is .8 m/s   please show/explain how to solve for this

A 156-gram baseball is hit toward the left by a bat. The magnitude of the force the bat exerts on the ball as a function of time is shown in (Figure 1). a) find the magnitude of the impulse that the bat impart to the ball (N*s) b)Find the direction of the impulse that the bat imparts to the ball c)Find the magnitude of the ball's velocity just after it is hit by the bat if the ball is initially at rest d)find the direction of the ball's velocity just after it is hit by the bat if the ball is initially at rest e)find the magnitude of the ball's velocity just after it is hit by the bat if the ball is initially moving to the right at 31 m/s  f)Find the direction of the ball's velocity just after it is hit by the bat if the ball is initially moving to the right at 31.0 m/s.

Hulk throws a ball that bounces off a wall and flies back at a speed of 132 meters per second. If the ball weighs 0.31-kilogram, and he initially threw the ball at a speed of 125 meters per second, what is the impulse applied to the ball by the wall? Do NOT include units Round your answer to the tenths place, include zeros if needed

Calculate the momentum pelephant of a 2020 kg elephant charging a hunter at a speed of 7.63 m/s. Pelephant kg-m/s Compare the elephant's momentum with the momentum Pdart Of a 0.0355 kg tranquilizer dart fired at a speed of 595 m/s. More information is needed to determine how the momentums compare. Pelephant = Pdart Pelephant Pdart What is the momentum Phunter of the 91.0 kg hunter running at 7.37 m/s after missing the elephant?

A 0.50-kg object travelling at +1.00 m/s collides with a 1.50-kg object that is travelling at -1.00 m/s.    They stick together after the collision. What is the final velocity on the combination? Determine the impulses on each to show they follow Newton’s 3rd law. Determine the change in kinetic energy.

A student on roller skates throws a basketball forward. How does the momentum of the student on skates compare to the momentum of the basketball? The velocity of the student is equal in magnitude but opposite in direction to the velocity of the basketball. The product of the mass times the velocity of the student is equal in magnitude and in the same direction as the product of the mass times the velocity of the basketball. The velocity of the student is equal in magnitude and in the same direction as the velocity of the basketball. The product of the mass times the velocity of the student is equal in magnitude but opposite in direction as the product of the mass times the velocity of the basketball.
