Assume friction is negligible in your calculations, so that the … How to Calculate and Solve for Mass, Height and Potential Energy v = Discharge Velocity. velocity 3. Mass & velocity to kinetic energy; Kinetic energy & velocity to mass; User Guide. F = mω²r F = 12 x 32² x 8 F = 12 x 1024 x 8 F = 98304. mass due to gravitation and it is 9.8 m/s (square), s is displacement or height which is 2 mile you will have to change it to the appropriate unit.That would do for initial speed,then use the equation v = u + at and you will have your answer. The question: A roller coaster is 100m above the ground, and weighs 1000kg. height The average velocity formula describes the relationship between the length of your route and the time it takes to travel. I got this answer wrong. After time t, the velocity changes, and the acceleration is 3 m/s2. Velocity v = 15 m/s. The product of the units of mass and velocity is the unit of Momentum. To compute for the kinetic energy, two essential parameters are needed and these parameters are mass (m) and velocity (v). find velocity The gravitational force lets it reach a certain height and then fall back down again. In the simplest terms, Velocity is object’s speed in a particular direction.
