7 ghder, that has a mass of 1640 kg, is initially moving at 20 m/s Nw. A wind accelerates the glidert 2.5 m/s 20° E of N for eight second. Then the wind shifts to 48° E of N accelerating the glider at1.8 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 windgust 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 kineticenergy at that time. Is this contention reasonable? Explain.

Since more than 3 sub parts are given , solution for the first three is provided here. Please…

An ice glider, that has a mass of 1640 kg, is initially moving at 20 m/s Nw. A wind accelerates the ginuet 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?
