Dr. Gundersen PHY201 Midtenn #1 September 22, 2021 [3.] A golf ball is hit from the origin at the surface of the Moon, and its path is described by the position vector 1"(t) = 8.66:2 + (5.001: 0.819)] where position is measured in meters and t is measured in seconds. Here i is parallel to the Moon's surface and] is directed upward and perpendicular to the Moon's surface. Assume there is no air friction (because there isn't!) and that the Moon's surface is at. [3A.] [8 points] What is the initial (t=0) speed and angle above the at Moon surface that the golf ball is hit? (Hint: Make a sketch showing the initial 3: and y components of the velocity.)
