Tom and his twin brother Tim have a combined mass of 300.0 kg and are zooming in an amusement park bumper car at 10.0 m/s. They bump Melinda’s car, which is sitting still. Melinda has a mass of 125.0 kg. After the elastic collision, the twins continue ahead with a speed of 4.12 m/s. How fast is Melinda’s car bumped across the floor? Group of answer choices

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
