Question:
What force would be necessary in Example 2.4 if the mass were 735 lbm?
Assume that on the surface of the Earth, g = 9.81 m/s2 = 32.2 ft/s2 (i.e., each to three significant figures). Make sure you are reporting the solution to the proper number of significant figures.
Example 2.4
What is the force necessary to accelerate a mass of 65.0 lbm at a rate of 15.0 ft/s2? Since the problem is stated in English units, assume the answer is required in these units. Equation (2.7) is the principle used here:
ft] [lbf x s?1 [Ibm] s2||Ibm x ft ma 65.0 x 15.0 F = = 30.3 Ibf 32.174

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
