The ball is served from rest and attains a speed of 131 mi/h ≈ 211 km/h ≈ 58.6 m/s.
a. If the racket is in contact with the ball over a distance of 0.15 m, then it applies a constant acceleration <em>a</em> such that
b. Since acceleration is constant, we can use the definition of average acceleration:
Solve for ∆<em>t</em> :
Answer: In direct current (DC), the electric charge only flows in one direction.
Electric charge in alternating current (AC<span>), changes direction periodically.
