a duck has a mass of 2.90kg. as the duck paddles, a force of 0.250 N in a direction of 55.0° south of east. When these forces begin to act, the velocity of the duck is 0.150 m/s in a direction due east. Find (a) the magnitude and (b) the direction (relative to die east) of the displacement that the duck undergoes in 2.10 s while the forces are acting. (Note that the angle will be negative in the south of east direction.)

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
