- In some problem, you are asked to calculate the mass of an object, and you get the following result: m=Fd/v. Where F is a force, V is speed, and d is distance. Check the units to see if this expression is acceptable.arrow_forwardA drag force is represented by vector a of magnitude 5.72 N and direction 148.6 degrees (measured from the +x-axis, counter-clockwise). If the gravitational force of a projectile is represented by vector bof magnitude of 11.2 N. The x-component of the Sum vector, sx (N) is:arrow_forwardThe mass M of the largest stone which can be moved by water of a flowing river is assumed to be.

- You are designing a spherical tank to hold water for a small village. The volume of liquid it can hold can be computed as V = th²(3h) where V = volume [m³], h = depth of water in tank [m], and R = the tank radius [m]. Use Newton Raphson method with 3 iterations to find the height (h=?) for storing 22 m³ of water with 7 m diameter-tank. Take T = 3.1416 and initial guess for h=R.
