A grasshopper hops along a level road. On each hop, the grasshopper launches itself at angle θ0 = 45ο and achieves a range R = 0.80 m. What is the average horizontal speed of the grasshopper as it hops along the road? Assume that the time spent on the ground between hops in negligible and achieves a range.
