Question:

To determine the gravitational acceleration at the surface of a newly discovered planet, scientists perform a projectile motion experiment. They launch a small model rocket at an initial speed of 50.0 m/s and an angle of 30.0° above the horizontal and measure the (horizontal) range on flat ground to be 2165 m. Determine the value of g tor the planet.
