Q. A rocket is launched at an angle of 58.0° above the horizontal with an initial speed of 105 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 29.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile.

Find the maximum altitude reached by the rocket.

Q. The dome of a Van de Graaff generator receives a charge of 0.00019 C. The radius of the dome is 7.1 m the coulomb constant is 8.98755e^9. and the acceleration due to gravity is 9.8 m/s^2 find the strength of the electric field 11.2 m from the center of the dome.
