Judge Thomas Lee Wyoming, If I multiply the terms in this expression, I get that the net work is equal to 1/2 mass times the final velocity squared minus 1/2 mass times the initial velocity squared. Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 4 = 27.8 m/s. Quick Formulas Average velocity = final position initial position final time initial time Average velocity if acceleration is constant = initial velocity final velocity Average velocity if acceleration is zero and constant = Final velocity = a = acceleration t = time Method 1 Finding Average Velocity 1 And you have the final speed. There are a couple of ways to do this, using motion equations or conservation of energy, that relate height, velocity, and the acceleration of gravity. To compute for the potential energy, three essential parameters are needed and these parameters are mass (m), height (h) and acceleration due to gravity (g). Enter one value at velocity and height, the other value will be calculated. So at any point in the fall, the rate at which it is trading height for velocity is equal to velocity divided by the gravitational constant. You know the initial velocity u, and also velocity is zero when the object reaches max height just before it starts to fall again. By using first, second and third equations of motion. Subtract your result from the object's initial upward velocity. Back in the Middle Ages, people believed that the heavier an object, the faster it would fall. Multiply the length of time the object has been falling by 9.8 meters per second squared.
