SUMMARY
The initial velocity required for a locust to jump 75 cm horizontally at a 55° angle is calculated to be 4.0 m/s using the equations of projectile motion. The solution involves equating the time of flight derived from vertical motion to that from horizontal motion, leading to the equation v²(0.47) = 7.36. The final velocity can also be confirmed using the formula R = v²(sin²Ɵ) / 2g, resulting in a different value of 2.8 m/s, indicating a discrepancy that warrants further investigation.
