Using the equation F=m•a What is the mass of a falling rock if it produces a force of 147 N? Hint: This is a free fall problem so a = 9.8m/s/s (acceleration of gravity).

15 kg

Explanation:

F = m(a)

147 N = m(9.8 m/s^2)

m = 147 N/9.8 m/s^2

m = 15 kg

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
