A grasshopper hops along a level road. On each hop, the grasshopper launches itself at angle θ0=45∘ and achieves a range R = 0.85 m .
1.) 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 is negligible.
Express your answer using three significant figures and include the appropriate units
Homework Answers
Range, R = u^2 sin2(theta) /g
0.85 = u^2 sin(90)/9.8
Initial speed, u = 2.89 m/s
Horizontal speed, vx = 2.89 cos45 = 2.04 m/s

A small, spring-loaded cannon launches a golf ball from level ground with an initial speed vi at an angle θi with the horizontal. The golf ball lands a horizontal distance R from its launch point. The highest point the golf ball reaches during its flight is a distance R/12 above the ground. In terms of R and g, find the following. (You may ignore air resistance.) (a) the time interval during which the golf ball is in motion t =...
