A car of mass m_auto = 1.20x10^3 kg travels west-east at a speed of 50.0 km/h, while a wagon of mass m_ wagon = 2.80x10^3 kg travels at a speed of 40.0 km/h in a south-north direction; vehicles collide at an intersection (Point A). From the above and assuming that the crash that occurred is considered a perfectly inelastic collision, determine the magnitude and direction of the velocity that will occur after the collision.
A 0.05 kg ball strikes a wall with a velocity v1 = -25 m/s and bounces back with a velocity v2 =5 m/s. If the collision lasts 0.2 s, then find the average force (in N) exerted on the ball.
In the railroad freight yard, an empty freight car of mass m rolls along a straight level track at 1.20 m/s and collides with an initially stationary, fully loaded boxcar of mass 5.80m. The two cars couple together on collision. (a)What is the speed of the two cars after the collision? ___m/s (b)Suppose instead that the two cars are at rest after the collision. With what speed was the loaded boxcar moving before the collision if the empty one was moving at 1.20 m/s? ___m/s
As shown in the figure below, two blocks (m1 and m2) are each released from rest at a height of h = 4.63 m on a frictionless track and when they meet on the horizontal section of the track they undergo an elastic collision. If m1 = 2.50 kg and m2 = 4.25 kg, determine the maximum heights (in m) to which they rise after the collision. Use the coordinate system shown in the figure. y1f=____m y2f=____m
A drunk driver in a 2100 kgkg car plows into a 2000 kgkg parked car with its brake set. Police measurements show that the two cars skid together a distance of 21 mm before stopping. If the effective coefficient of friction is 0.74, how fast was the drunk going just before the collision?
When analyzing collisions using the law of conservation of momentum, the same principles that allow us to analyze collisions in one dimension can also be used to analyze collisions in two dimensions. To do this, you must separately apply the law of conservation of momentum in the x- and y-directions. Use the following example to practice this process: Two football players are about to collide with one another. Player 1 has a mass of 98.1 kg and is moving with a velocity of 4.52 m/s, 21.5° east of north. Player 2 has a mass of 79.4 kg and is moving with a velocity of 5.15 m/s, 8.55° east of south. Find the x- and y-components of the momentum of each player. What is the sum of the momenta in each dimension? If, when the players collide, they hold onto each other and move as a single unit, what will be the velocity vector of that single unit? Suppose that the two players collide, and bounce off each other. If player 2 is sent backwards with a velocity of 1.77 m/s, 15.5° west of north,…
In an experiment ball-1 of mass 0.9 kg is let it to go down on the ramp from rest from the height of 1.2 m above the table. At the bottom of the ramp, it finds ball-2 of mass 1.4 kg sitting at the edge of the table 1.2 m high. After the collision both balls fly off the table giving a sense of projectile motion.

A bumper car slides along a horizontal surface on which the coefficient of kinetic friction is 0.2. Its velocity at point 1 is 5.75 m/s and at point 2 is 4.00 m/s. Use the impulse-momentum theorem to find how long it takes the bumper car to travel from point 1 to point 2.
