The drag force for falling objects due to air friction depends on the velocity of the object and is given by the equation drag = b where b is a constant that depends on the fluid through which the object moves and the radius of the object. (a)find the terminal speed of an object of mass 59.0 kg for which b = 11.0 kg/s. (b) will the terminal speed be different if the object's initial speed is different?

One object (m 1) has a mass of 2 kg and moves with a speed of 9 m/s to the right. another object (m 2) has a mass of 3 kg and moves to the left with a speed on 3 m/s. the two objects collide. after the collision, the first object (m 1) moves to the right with a speed of 1.5 m/s. the second object (m 2) moves to the right at 2 m/s. what is the change in the momentum of the first object (m 1) during the collision? (remember that "change" is always "final − initial".)
