Problem: A grasshopper hops down a level road. On each hop, the grasshopper launches itself at angle 45 degree and achieves a range R = 1.4 m.
Part A: 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.
I need help to solve the above problem and express your answer using two significant figures.
