1) a .75 disk rolls down a 10m ramp. how many revolutions does it complete.
2) a uniform solid disk starts at 52 rad/s. to rest, it does 3900j of work. it has a radius of 1.2m. how long does it take to stop and how far does it go? (1/2mr^2)
3) a wheel is rotating at a constant rotational acceleration. what is true?
4) if you release a hoop, disk, and sphere at the same time from a ramp, what will have the greatest rotational acceleration.
5) 2 cylinders rotate counter clockwise are brought together. what is their rotational speed after? (one wheel has constants all of 1, the second one has constants all of 2)

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

statement #3 on andre"s list is false.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
