A 0.0270-kg BB traveling at 200.0 m/s east hits a motionless 3.30-kg block and bounces off it, retracing its original path with a velocity of 100.0 m/s west. What is the final velocity of the block? Assume the block rests on a frictionless horizontal surface. If the final velocity of the block is toward east, enter a positive value and if the final velocity of the block is toward west, enter a negative value. m/s

A ball traveling with an initial momentum of 0.9 kg⋅m/s bounces off a wall in the opposite direction with a momentum of -0.5 kg⋅m/s. What impulse vector was needed to do this? (Remember: One dimensional vectors use + and - signs for direction!)

A 0.1 kg ball hits a wall at right angles to the surface and bounces off. Before the collision, the ball’s velocity component perpendicular to the wall is vi,x = −8 m/s. After the collision, it is vf,x = +6m/s. What is ∆px, the change in the ball’s momentum perpendicular to the wall? A. −1.4kgm/s B. +1.4kgm/s C. +0.8kgm/s D. −0.6kgm/s E. −0.2kgm/s

Two cars approach an ice-covered intersection. One car, of mass 1.15*10^3 kg, is initially traveling north at 11.1 m/s. The other car, of mass 1.65*10^3 kg, is initially traveling east at 11.1 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision.

Two cars approach an ice-covered intersection. One car, of mass 1.25 103 kg, is initially traveling north at 11.1 m/s. The other car, of mass 1.58 103 kg, is initially traveling east at 11.1 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision. Please provide magnitude & direction (ex - 30 degrees North of West)

A car with a mass of 980 kg is initially traveling east toward
an intersection with a speed of vc = 20.9 m/s
and a 1500 kg pickup is traveling north toward the same
intersection. The car and truck collide at the intersection and
stick together. After the collision, the wreckage (car and truck)
moves off in a direction of 44.0° above the x-axis.
Determine the initial speed of the truck and the final speed of
the wreckage in meters...
