What is the force of gravity on a 75 Kg box that is resting on the surface of the Earth? What if the box was at a distance twice as far as the radius of the Earth?

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

Individuals who live below the poverty line get seriously ill more often than those who do not what could be the hidden variable in this situation?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
