ghder, that has a mass of 1640 kg, is initially moving at 20 m/s Nw. A wind accelerates the glider t 2.5 m/s 20° E of N for eight second. Then the wind shifts to 48° E of N accelerating the glider at 1.8 m/s for 11 seconds. 1) What is the glider's initial kinetic energy? 2) What is the glider's velocity at t= 8 s? 3) How much energy did the wind transfer to the glider during the 8 s? 4) What was the glider's velocity after the 11 s the second wind gust was active? 5) How much energy did the wind transfer to the glider during the 19 s? 6) What was the glider's average speed fromt = 0 s to t = 19 s? 7) What was the glider's displacement from t=0s to t= 19 s? 8) What was the glider's average velocity from t 8 s to t 19 s? 9) What was the glider's final kinetic energy? 10) A student contends that the glider will have the largest force at t= 19 s since it has the most kinetic energy at that time. Is this contention reasonable? Explain.
