Two objects of mass 8 g and 5 g, respectively, move parallel to the x-axis, as shown. The 8 g object overtakes and collides with the 5 g object. Immediately after the collision, the y-component of the velocity of the 8 g object is 9 m/s upward. What is the y-component of the velocity ~v of the 5 g object immediately after the collision? 1. ~vy = 14.4 m/s upward2. ~vy = 5.625 m/s downward3. ~vy = 9 m/s upward4. ~vy = 9 m/s downward5. ~vy = 5.625 m/s upward6. ~vy = 14.4 m/s downward

A car with a mass of 980 kg is initially traveling east toward an intersection with a speed of vc = 20.2 m/s and a 1500 kgpickup 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 43.0° above the x-axis. Determine the initial speed of the truck and the final speed of the wreckage in meters per second. initial speed of the truck m/sfinal speed of the wreckage m/s

A knife thrower throws a knife toward a 300 g target that is sliding in her direction at a speed of 2.30 m/s on a horizontal frictionless surface. She throws a 22.5 g knife at the target with a speed of 38.0 m/s. The target is stopped by the impact and the knife passes through the target. Determine the speed of the knife (in m/s) after passing through the target.

Chapter 07, Problem 30 GO One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 24 m/s. The masses of the two objects are 3.2 and 7.9 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is the one moving initially and the case (b) when the small-mass object is the one moving initially. (a) Vf = (b) Vf =

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.

Two objects, A and B, with masses 3.2 kg and 1.8 kg, move in a frictionless horizontal surface. Object A moves to the right at a constant speed of 5.1 m/s while object B moves to the right at a constant speed of 1.4 m/s.  They collide and stick together. a) Find the total kinetic energy of the system after the collision. b) Is the kinetic energy of the system conserved?  Explain.

Question Vị = 8 m/s A Vi = 16 m/s Objects A and B (Mass A = 6kg, Mass B = 4kg) have a head-on collision as shown. Immediately before the collision, Object A has a velocity of 8 m/s to the right, and Object B has a velocity 16 m/s to the left. Immediately after the collision, Object A has a velocity 4 m/s to the left. What is the magnitude and direction of the velocity of Object B ilmmediately after the collision? %3D Answer

A bullet of mass m = 8.00 g is fired into a block of mass M = 240 g that is initially at rest at the edge of a table of height h = 1.00 m (see figure below). The bullet remains in the block, and after the impact the block lands d = 1.80 m from the bottom of the table. Determine the initial speed of the bullet. m/s
