Question

Acceleration due to gravity on planet A is nine times that on planet B. A person jumps to a height of 2 m on A. How high would the same person jump on B with the same take-off speed?

G1 Physics · Accepted Answer

Step 1: For a given initial upward speed u, maximum height H=u²/(2g). Step 2: Hᵦ/Hₐ=gₐ/gᵦ=9, so Hᵦ=9×2=18 m. Final answer: B — 18 m.
