Q. A 46.0-kg projectile is fired at an angle of 30.0° above the horizontal with an initial speed of 1.44 102 m/s from the top of a cliff 162 m above level ground, where the ground is taken to be y = 0.
(a) What is the initial total mechanical energy of the projectile?
(b) Assume the projectile is travelling 102.1 m/s at its maximum height of y = 378 m. How much work has been completed on the projectile by air friction?
(c) What is the speed of the projectile immediately before it hits the ground if air friction does one and a half times as much work on projectile when it is going down as it did when it was going up?
Two point charges, Q1 = -7 and Q2 = 2 are located between two oppositely charged parallel plates. The two charges are separated by a distance of x = 0.33m. Assume that the electric field produced by the charged plates is uniform and equal to E = 6..

explain the electric flux through the surface of the cube. Calculate the volume charge density of the atmosphere, assuming it to be uniform between 270 and 420 m.
The wheel of a car has a radius of 0.365 m. The engine of the car applies a torque of 284 N · m to this wheel, which does not slip against the road surface. Since the wheel does not slip, the road should be applying a force of static friction to t..
