During which time the spring is stretched by only 0.0500 m. Find a) the spring constant of the spring and b) the coefficient of kinetic friction between the block and the table.
The first-order bright fringe is a distance of 4.84 from the center of the central bright fringe. For what wavelength of light will the first-order dark fringe be observed at this same point on the screen?
What is the y-component of the impulse of the net force applied to the ball? What is the x-component of the final velocity of the ball? What is the y-component of the final velocity of the ball?
A 78.0 kg boy and a 59.0 kg girl use an elastic rope while engaged in a tug-of-war on an icy, frictionless surface. If the acceleration of the girl towards the boy is 2.27 m/s2, find the magnitude of the acceleration of the boy toward the girl.
In a Young's double-slit experiment, two rays of monochromatic light emerge from the slits and meet at a point on a distant screen, as in the drawing. The point on the screen where these two rays meet is the 4th-order bright fringe. The difference
The magnitude FN of the normal force that each side of the tread channel exerts on the stone is 1.8 N. Assume that only static friction supplies the centripetal force, and determine the radius r of the tire.
