An object of mass m has these three forces acting on it (there is no normal force, "no surface"). F1 = 7 N, F2 = 7 N, and F3 = 5 N. When answering the questions below, assume the x-direction is to the right, and the y-direction is straight upwards.
a) What is the net force in component form, in terms of F1, F2, F3, and the unit vectors i and j
b) What is the magnitude of the net force, in newtons?
c) What is the angle , in degrees, of the net force, measured from the +x-axis? Enter an angle between -180° and 180°.
d) What is the magnitude, |a| of the acceleration, in meters per square second, if the block has a mass of 8.5 kg?
