A 8.00-kg mass moving east at 15.0 m/s on a frictionless horizontal surface collides with a 10.0-kg mass that is initially at rest. After the collision, the 8.00-kg mass moves south at 4.00 m/s. (a) What is the velocity of the 10.0-kg mass after t

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.
