How much time elapses before compass hits the ground : A space vehicle is coasting at a constant velocity of 28.5 m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.523 m/s2 in the +x direction.
What is the x-component of total electric field at p : A ball of mass 1.020 g and positive charge q =45.2 microC is suspended on a string of negligible mass in a uniform electric field.
