A ball of mass 0.25 kg glances of a wall as shown in the diagram. The ball approaches at 15 m/s at 0-30° and leaves at 12 m/s at p=20°. The collision lasts for 15 milliseconds. (a) What are the components of the impulse experienced by the ball? (b) What are the components of the average force acting on the ball?

Determine the velocity of the disk A just after collision. Express your answer to three significant figures and include the appropriate units.

can you pls also draw a picture/representation of the scenario described? Thanks so much!

A raliway wagon A of mass 12 x 103 kg coasting at 1.2 m/s on a horizontal track crashes head-on and couples with a wagon B of mass 10 x 103 kg coasting at 1 m/s in the opposite direction, as shown in Figure 6. Determine: a) the common speed of the wagons just after collision assuming that the wheels are free to roll during collision%3B b) the average force between the two wagons, if the coupling takes place in 0.9 s. 1.2 m/s 1 m/s B
