What is the magnitude of the force f⃗ on the -10 nc charge shown in (figure 1)?
express your answer using two significant figures.
what is the direction of the force f⃗ on the -10 nc charge in the figure? give your answer as an angle measured cw from the +x-axis.

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
