1. An airplane is descending at an angle of 20 deg with respect to the horizontal when it drops a bomb. If the altitude of the plane at the time the bomb is released is 5000 meters and the speed of the plane is 750 km/h; determine the range (horizontal distance traveled) of the bomb and the velocity at which it hits the ground.
what is the velocity of plane with respect to the ground. A nonconducting sphere has radius R = 2.53 cm and uniformly distributed charge q = +6.00 fC. Take an electric potential at the sphere's center to be V0 = 0.
