A proton, moving with a velocity of v1i collides elastically with another proton that is initially at rest. One proton has three times the speed of the other after the collision. How would I find the speed of each proton after the collision in terms of vi and their velocity vectors after the...
Lost in this review problem:
Most of us know intuitively that in a head-on collision between a large dump truck and a subcompact car, you are better off being in the truck than in the car. Why is this? Many people imagine that the collision force exerted on the car is much greater than that...
In the Atwood machine regular 2 mass machine,m1= 2.20kg and m2=7.30kg . The masses of the pulley and string are negligible by comparison. The pulley turns without friction and the string does not stretch. The lighter object is released with a sharp push that sets it into motion at an initial...
