A 1500 kg car traveling eastwards at 25 m / s collides with a 2500 kg load truck going north at a speed of 20 m / s as shown in the figure. Find out the magnitude and direction of the speed of the wreck after the collision, taking into account that the vehicles had a completely inelastic collision.

In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0315 kg and the mass of the pendulum is 0.250 kg, how high ℎ will the pendulum swing if the marble has an initial speed of 5.65 m/s? Assume that the mass of the pendulum is concentrated at its end so that linear momentum is conserved during this collision.

A steel ball of mass 0.600 kg is fastened to a cord that is 80.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal. At the bottom of its path, the ball strikes a 3.00 kg steel block initially at rest on a frictionless surface. The collision is elastic. (a) Find the speed of the ball just after collision. (No Response) m/s (b) Find the speed of the block just after collision. (No Response) m/s

A steel ball of mass 0.440 kg is fastened to a cord that is 80.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure. At the bottom of its path, the ball strikes a 3.10 kg steel block initially at rest on a frictionless surface. The collision is elastic. Find (a) the speed of the ball and (b) the speed of the block, both just after the collision. (a) Number i (b) Number Unit Unit

A bullet of mass m = 8.00 g is fired into a block of mass M = 240 a 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 = 1.50 m from the bottom of the table. Determine the initial speed of the bullet. Use the given information to find the velocity of the block after collision with the bullet and then use conservation of momentum to find the initial speed of the bullet. m/s Need Help?

A cue ball traveling at 6.57 m/s makes a glancing, elastic collision with a target ball of equal mass that is initially at rest. The cue ball is deflected so that it makes an angle of 30.0° with its original direction of travel. (a) Find the angle between the velocity vectors of the two balls after the collision.   (b) Find the speed of each ball after the collision.

A cue ball initially moving at 4 m/s strikes a stationary eight ball of the same size and mass. After the collision, the cue ball’s final speed is 1 m/s. Find the cue ball’s angle θ with respect to its original line of motion. This is considered an elastic collision.

A steel ball of mass 0.400 kg is fastened to a cord that is 80.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal. At the bottom of its path, the ball strikes a 2.00 kg steel block initially at rest on a frictionless surface. The collision is elastic. (a) Find the speed of the ball just after collision. m/s (b) Find the speed of the block just after collision. m/s

Situation 7. A ball of mass 0.220 kg that is moving with a speed of collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.8m/s.    C. Supposed that a ball is dropped from a height of 2.60 m. If the coefficient of restitution between the ball and the ground is 0.60, to what height will it bounce?
