W = K E = 1 2 m v 2. 3. Step 1. The total mechanical energy of an object with mass mm at height hh in a closed system can be written as ME = 12mv2 + mghME = 12mv^2 + mgh. Nhân cả hai vế của phương trình với 2 2.00 min 60.e the initial velocity of the will be always .1. Solve for v, the velocity of the object, in terms of the given quantities. The estimated quotient is 100.

Why is the formula 1/2mv^2 and not just mv^2 when working out

But with friction it does take force to move at constant velocity. Multiplying by m should easily let you get to mV^2 / 2 . SOLUTION: The total mechanical energy of an object with mass m at height h in a closed system can be written as ME = 1/2mv^2 + mgh. Note that if the cylinder slid without friction down the incline without rolling, then the entire gravitational potential energy would go into translational kinetic energy. Share: Share.
