Question1

A small metal sphere, carrying a net charge of = -3.00, is held in a stationary position by insulating supports. A second small metal sphere, with a net charge of = -7.40 and mass 1.40, is projected toward. When the two spheres are 0.800 apart, is moving toward with speed 22.0. Imagine that the two spheres can be treated as point charges. You can overlook force of gravity. What is the speed of while the spheres are 0.440 apart?

Question2

Attempting to stop on a slippery road, a car moving at 88 km/h skids at 30 degrees to its initial motion, stopping in 3.8 seconds. Determine the average acceleration in m/s^2, in coordinates with the x-axis in the direction of an original motion and the y-axis toward the side to which the car skids.
