Professional baseball pitchers deliver pitches that can reach the blazing speed of 100 mph (miles per hour). a local team has drafted an up-and-coming, left-handed pitcher who can consistently pitch at 43.35 m/s (97.00 mph) . assuming a pitched ball has a mass of 0.1422 kg and has this speed just before a batter makes contact with it, how much kinetic energy does the ball have?

Work out sian speed for the first 30 minutes of her journey. give your answer in km/h.
