How much would an 80.0kg person weigh on Mars, where the acceleration of gravity is 3.93m/s and in Earths moon, where the acceleration of gravity is 1.63m/s

2(a): determine expressions for its acceleration ax(t), velocity vx(t), and position x(t), given that its initial acceleration, velocity, and position are ai, vi, and xi, respectively. (use any variable or symbol stated above as necessary.)
