A blue car with mass mc = 480.0 kg is moving east with a speed of vc = 23.0 m/s and collides with a purple truck with mass mt = 1288.0 kg that is moving south with a speed of vt = 10.0 m/s . The two collide and lock together after the collision.
What is the magnitude of the initial momentum of the car?
What is the magnitude of the initial momentum of the truck
What is the angle that the car-truck combination travel after the collision? (give your answer as an angle South of East)
What is the magnitude of the momentum of the car-truck combination immediately after the collision
What is the speed of the car-truck combination immediately after the collision?
assume the roller coaster (h1 = 34 m, h2 = 10 m, h3 = 20) passes point A with a speed of 2.00 m/s. If the average force of friction is equal to one sixth of its weight, with what speed will it reach point B? The distance traveled is 45m.

In lectures and in tutorials, we discussed the confinement of an electron (or other particle) to a box of infinite depth, running from x = 0 to x = a. If we, instead, define this 1-D region of confinement as running from -(a/2) to (a/2)
