Determining final velocity using initial velocity and displacements
A 5 kg bowling ball is rolled back to the bowler over a ramp system. If the ball is given an initial velocity of 0.6 m/s at its starting point's height which is 100 cm, what is the balls velocity at its ending point at 40 cm, after going over a height of 45cm first? So the ball leaves the first position goes through a dip up to 45 cm and ends at 40 cm.© SolutionLibrary Inc. solutionlibary.com 9836dcf9d7 https://solutionlibrary.com/physics/classical-mechanics/determining-final-velocity-using-initial-velocity-and-displacements-1l1
...n in space, 100 cm above the ground. Let's use meters as our units so that our energies come out in Joules.
Potential energy (P) = mass * height * gravitation
P = mgh
P = 5*9.8*1
The ball also has some kinetic energy
(K) = 0.5*mass*speed^2
K = 0.5mv^2
K = 0.5*5*(0.6^2)
Now, if this is a conservative system (if there is no friction or air resistance, etc) then the total energy will be the same at the beginning and end of the ball's journey. ...
