Croquet balls all have a mass of 0.5kg. The green ball is moving at 12.0m/s and strikes a blue ball which is still after the collision the green ball continues to move at 2.4m/s in the same directio
A 8.4 kg mass is attached to a light cord that passes over a massless, frictionless pulley. The other end of the cord is attached to a 3.7 kg mass.
A 4.0 kilogram cart moving to the right and a 6.0 kilogram cart moving to the left on a horizontal frictionless surface. When the two carts collide they lock together.
Christian Ramirez: A small 0.12kg metal ball is tied to a very light sting 0.80m long to form a pendulum that is then set swinging by releasing the ball from rest when the string makes a 45 degree a

The magnitude of the decelerating force equals 360 N, and the time during which the deceleration takes place is 10.0 s. What is the final speed of the man and the car?
What factors affect bacterial growth and the growth of other microbes? How can the knowledge of these factors help in controlling bacterial growth? What methods are used to control the bacterial gr
A 5.0 kg ball is initially sitting at rest on top of a 48 meter hill. The ball is pushed with a force of 25 N for 3.0 s toward the edge of the hill. Upon reaching the edge, the ball is allowed to r
There are some cardinal signs of acute inflammation. Can you describe the underlying mechanisms responsible for these cardinal signs of acute inflammation including heat, pain, redness and swelling?
Assume that a scale is in an elevator on Earth. What force would the scale exert on a 57.6kg person on it if the elevator slows down at a rate of 1.62m/s^2 while moving downward?
