Full solution

1) A long-jumper leaves the ground at an angle of 20.0 above the horizontal and at a speed of 11.0 m/s. (a) How far does he jump in the horizontal direction? (b) What is the maximum height reached? 2. A plane is flying at 290 km/h 420 S of E relative to the air when the wind velocity is 65 km/h 250 N of E . Calculate the velocity of the plane relative to the ground
