Zoologists have studied the mechanics of locust jumping. When a locust jumps, as depicted in the figure, the resultant force R
exerted by the hind legs is the sum of two forces. The first force W acts directly downward to support the locust's weight, which
is about 0.02 newton. The second force F is for the takeoff; its magnitude is about 0.29 newton, and the direction makes an
angle of 55° with the horizontal.
