Assume that the object is at x = 0 when t = 0. x(m) v(m/s) t(s) a(m/s ) 2 t(s) t(s) 20 40-20-40 5 10 5 10 5 10 5 10-5-10 5 10-5-10 3 4. A ski jumper leaves the jump at an angle of 20 above horizontal with a speed of 25.0m/s. Her flight lasts 4.00s. Find the distance of the horizontal portion of the flight and vertical drop involved. 5. The moon orbits earth once every 27.4days. The distance between the earth and the moon is 3.84x10 8 m. Use this data to find the velocity and acceleration of the moon. Describe the direction of each vector....
