In 1993, Wayne Brian threw a spear at a record distance of 201.24 m. (This is not an official sports record because a special device was used to āelongateā Brianās hand.) Suppose Brian threw the spear at a 35.0Ā° angle with respect to the horizontal. What was the initial speed of the spear? 2. Find the maximum height and time of flight of the spear in problem #1. I really don't know how to do any of this please help me :(
