Question
A rock thrown with an initial velocity of 35 m/s at an angle of 48° with respect to the horizontal has a range of 963 m on a certain planet. What is the acceleration of gravity on this planet?

time in air (consider the vertical vector)
hf=hi+35Sin48*t-1/2 g t^2
0=t(35sin48-g/2 t)
t= 70/g sin48
range= 35cos48 t put the t above in , and solve for g.
