A stone is shot from the edge of a cliff 125 m above ground level with an initial speed of 65 m/s at an angle of 37 degree below the horizontal. (a) Determine the the displacement along x direction
Ball A is dropped from the top of a building of height h at the same instant that ball B is thrown vertically upward from the ground. When the balls collide, they are moving in opposite directions, and the speed of A is 3 times that of B. At what
So the voltage equation for a Van de Graaff generator in the region outside the dome, r > R, is the same as that for a point charge with the same total charge.)
A 1.87-m-long, 552 g rope pulls a 4.4 kg block of ice across a horizontal, frictionless surface. The block accelerates at 1.65 m/s2. How much force pulls forward on the ice?
Consider a completely isolated, thick, conducting infinite slab. one face-off the slab has a uniform surface charge density, s. 1. What is the electric field of the slab?
A parallel-plate capacitor has an area of 5.50 cm2, and the plates are separated by 1.06 mm with air between them. It stores a charge of 314 pC. What is the potential difference across the plates of the capacitor?
What is the area of the plates of a 2 F parallel plate capacitor, given that the separation between the plates is 0.5 cm?
An 8.78-kg block slides with an initial speed of 1.62 m/s down a ramp inclined at an angle of 27.1° with the horizontal. The coefficient of kinetic friction between the block and the ramp is 0.77. Use energy conservation to find the distance t
A mass m1 = 5.7 kg rests on a frictionless table and connected by a massless string to another mass m2 = 3.8 kg. A force of magnitude F = 36.0 N pulls m1 to the left a distance d = 0.77 m. 1) How much work is done by the force F on the two block s
A student is standing at the edge of a rotating circular platform of mass 200kg and radius 1.1 m. The student of mass 70 kg walks slowly toward the center of the platform. If angular velocity of the system is 2 rad/s initially, what is the angular
