A starship has a mass of 8,500kg. It is moved by Yoda, 3.2m vertically upward and 14.8m horizontally toward Yoda, and it took 4 seconds to that diagonal motion. Pretend that it is on a planet where gravity is 5m/s^2.
a) Determine the amount of force used to lift the ship.
b) what magnitude in Newtons.
c) what angle did Yoda apply the force in order to cause the observed acceleration?
Two particles are fixed on x-axis. Particle 1 of charge q1 = -2×10^-7 C at x = 20 cm and particle 2 of charge q2 = +8×10^-7 C at x = 70 cm. At what x coordinate on the axis is net electric field produced by the particles equal to zero.
