On a frictionless surface. a block of mass M moving at speed v collides elastically with another block of the same mass that is initially at rest. After the collision, the first block moves at an angle θ to its initial direction and has a speed U/2. The second block's speed after the collision is 3 4 (B) 2 2 U) (E) ut cose

A child applies a force F parallel to the z-axis to a 6.00 kg sled moving on the frozen surface of a small pond
A child applies a force F parallel to the z-axis to a 6.00 kg sled moving on the frozen surface of a small pond. As the child controls the speed of the sled, the 2-component of the force she applies varies with the 2-coordinate of the sled as shown in figure (Figure 1). Suppose the sled is initially at rest at x = 0. You can ignore friction between the sled and the surface of the pond. For related problemsolving tips...

A 1000-kg car moving at 30m/s due north collides completely elastically with a 1250-kg truck heading north of east. After the collision the truck is moving due north and the car is moving due east. Find the initial speed of the truck. I think the answer is 34m/s and we have to break it up into x and y component and equate them but please tell me the theory behind it. Thanks

Two objects slide towards each other across a frictionless surface. Object 1 with a mass of 3.50 kg initially slides to the east with a speed of 0.750 m/s. Object 2 slides in the direction 30.0◦south of west with a speed of 1.25 m/ s. After colliding, the two objects stick together and slide due south. What is the final speed of both objects after the collision?
