Q1. An airplane is flying with a velocity of 83.0 at an angle of 22.0 above the horizontal. When the plane is a distance 114 straight above a dog that is standing on level ground, a suitcase drops out of the luggage compartment.
Q2. A ball of mass 1.024 g and positive charge q =40.3microC is suspended on a string of negligible mass in a uniform electric field. We observe that the ball hangs at an angle of theta=15.0o from the vertical. What is the magnitude of the electric field?
