A hokey tablet of mass m is tied to a rope that runs through the center of a table. The pill moves in a circle of radius r. At the other end of the rope hangs a mass m. Consider that the
table surface is perfectly smooth. What is the expression of the speed of the hokey pickup
if the mass m remains at rest?

What properties of a moving object are used in determining the object's energy of motion

Name two kinds of practical electric pumps.

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
