Explanation & answer:
Assuming a smooth transition so that there is no abrupt change in slopes to avoid frictional loss nor toppling, we can use energy considerations.
Initially, the cube has a kinetic energy of
KE = mv^2/2 = 10 lbm * 20^2 ft^2/s^2 / 2 = 2000 lbm-ft^2 / s^2
At the highest point when the block stops, the gain in potential energy is
PE = mgh = 10 lbm * 32.2 ft/s^2 * h ft = 322 lbm ft^2/s^2
By assumption, there was no loss in energies, we equate PE = KE
322h lbm ft^2/s^2 = 2000 lbm ft^2/s^2
=>
h = 2000 /322 = 6.211 (ft)
distance up incline = h / sin(30) = 12.4 ft

because every time you dived a number by its own number it is 1
Answer:
=> The total numbers of cylinders on the engine.
=> Total number of lobes in the cam ring.
=> The direction at which the cam ring rotates.
Explanation:
A cam is a kind of ring and a device that is being used in engines. One or the main purpose of using cams in engines us because it helps in the change or transformation of the rotational movement of the engine to a translational one. Instead of using a cam ring, a cam roller can be used in place.
There are three things that can be used to to determine the speed of cam ring speed and they are given below as;
=> The total numbers of cylinders on the engine.
=> The Total number of lobes in the cam ring.
=> The direction at which the cam ring rotates.
