A bowling ball of mass 7.20 kilogram and radius 10 centimeter rolls without slipping down a lane at 3.50 m/s. Compute its total kinetic energy.
at a given instant a particle with a mass of 5.00 x 10-3 kg and a charge of 3.50 x 10-8 c has a velocity with a
You have to do 2.2 kJ of work to push a 78-kg trunk 3.1 m along a slope inclined upward at 22 degrees , What is the coefficient of friction between trunk and slope
A charge = 5.00 is placed at the origin of an xy-coordinate system, and a charge = -4.50 is placed on the positive axis at 4.00 . If a third charge = 3.50 is now placed at the point 4.00 , 3.00 find the and components of the total force exerted on th..
The force applied to the cart in Question A by springscale F1 is still 12.25 N. What are the magnitude and direction of the frictional force
A double-slit interference pattern has a fringe (a “fringe” is an interference maximum) spacing of 4.0 mm. How far from the central maximum is the first position at which the intensity is equal to I1, the intensity due to each individual slit? In thi..
