This flywheel has a mass moment of inertia of 0.2 kgm2 and rotates at 53500 RPM. Calculate the kinetic energy ?

a 98 K crate is pushed to the top of a 2.5m ramp, which is inclined at 18 degrees with the horizontal. what is the potential energy of the crate?

a pendelum with a mass of 2.5 kg is released from a height of 3.6 cm above the height of the lowest position. how fast will the pendelum be moving when it passes through the point of its swing?

the following system (fig1) is in epuilibrium in the system a block of m=9 kg is attaehed the ceiling by two massless ropes are 45 of each two

thanks a lot Jhon K:*
