A 10.0 g marble slides to the left at a speed of 0.400 m/s on the frictionless, horizontal surface of an icy New York sidewalk and has a head- on, elastic collision with a larger 30.0 g marble sliding to the right at a speed of 0.200 m/s. 0.200 0.400 m/s 30.0 g 10.0 g a) Find the velocity of each marble (magnitude and direction) after the collision. Note: Since the collision is head-on, all motiom is along a line...
(8e28p44) A metal wire of mass m = 0.250 kg slides without friction on two horizontal rails spaced a distance d = 0.18 m apart, as in the figure. The track lies in a vertical uniform magnetic field B = 0.60 T. There is a constant current i = 0.30 A through generator G, along one rail, across the wire, and back down the other rail. Find the speed and direction of the wire's motion as a function of time,...

On a planet having g= 10m/s^2, a 2kg mass, starting from rest, slides down a frictionless in life on to a frictionless horizontal surface. The speed of the mass on the horizontal surface is 10m/s. A) Determine the height h at which the box began its slide. consider again the same frictionless incline. However, upon reaching the horizontal surface, a surface having friction is encountered. B) If when the mass starts from the same height as in part A), the...
