A50.0-g super ball traveling at 25.0 m/s bounces off a brick wall and rebounds at 22.0 m/s. a
high-speed camera records this event. if the ball is in contact with the wall for 3.50 ms, what is the
magnitude of the average acceleration of the ball during this time interval?

Explanation:

Average acceleration is change in velocity over time.

a = Δv / Δt

a = (22.0 m/s − (-25.0 m/s)) / 0.00350 s

a = 13,400 m/s²

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
