The fast server in women's tennis is Venus Williams, who recorded a serve of 130 (209) in 2007. If her racket pushed on the ball for a distance of 0.10, How much would be the average acceleration of the ball during her serve?
Ball final speed = 209 km/hr = 58.12 m/s Racket displacement = 0.1 meters Using the equation of motion: 2as = v² - u² Where the initial velocity u is 0 a = (58.12)²/2 * 0.1 a = 16,889.7 m/s²
