Chapter 3, Problem 40P
(II) A grasshopper hops down a level road. On each hop, the grasshopper launches itself at angle θ0 = 45° and achieves a range R = 1.0m. What is the average horizontal speed of the grasshopper as it progresses down the road? Assume that the time spent on the ground between hops is negligible.
