Two runners of mass 70 kg and 60 kg,respectively, have a total linear momentum of 350 kg*m/s. The heavier runner is running at 2.0m/s. Determine the possible velocitis of the lighter runner.
An emf is induced in a conducting loop of wire 1.11m long as its shape is changed from square to circular.Find the average magnitude of induced emf if the change in shape occurs in 4.03s and the local 0.135-T magnetic field is perpendicular to the ..
Treat the ball as a uniform, solid sphere, ignoring the finger holes. Illustrate what is the acceleration of the center of mass of the ball?
A 23 kg body is moving in the direction of the positive x axis with a speed of 292 m/s when, owing to an internal explosion, it breaks into three pieces.
Estimate the wavelength of the light.
Illustration on Eratosthenes' process
The tape is now wound back into the drum at angular rate. With what speed would the end of the tape move? (Note that our drawing specifies that a positive derivative of implies motion away from the drum. Be careful with your signs. The fact that the ..
how far from the woman will he be now. How various revolutions will the car have gone through when the magnitude of its total acceleration is 3.30 m/s^2.
A 18.60 kg piece of zinc at 75 degrees Celsius is placed in a container of water. The water has a mass of 20 kg and has a temperature of 10.10 degrees Celsius before the zinc is added. What is the final temperature of water and zinc.
A shopper in a supermarket pushes a loaded 28 kg cart with a horizontal force of 12N. How far will the cart move in 3.5s, starting from rest.
As a positron moves through a region of space, its speed increases from 2.80 X10^6 m/s to 8.00 X10^6 m/s. The electric force is the only force acting on the positron. Across what potential difference did the positron travel?
determine the distance between the centers of the two plates.
When verticaly falling sand hits a horizontally moving cart, the cart slows. avoid any friction between the cart and the tracks. Give two reason for this, one in terms of a horizontal force acting on the cart, and one terms of momentum conservatio..
