The angular velocity of a flywheel obeys the equation of , where and . Through what angle, in radians, does the flywheel turn during the first 5 s? Round your answer to three significant figures. 

A large metal turntable in the shape of a flat uniform disk has a radius of 2.00 m and a total mass of 120 kg. The turntable is initially rotating at about a vertical axis through its center. Suddenly, a 70.0 kg package dropped from an airplane lands at the very edge of the turntable. Calculate the angular speed of the turntable after the package lands. (Assume that you can treat the package as a particle.). Use three significant digits.

A 50.0 kg grindstone is a solid disk 0.520 m in diameter. You press an ax down on the rim with a normal force of 160 N. The coefficient of kinetic friction between the blade and the stone is 0.60, and there is a constant friction torque of between the axle of the stone and its bearings. How much force must be applied tangentially at the end of a crank handle 0.500 m long to bring the stone from rest to in 9.00 s? Use three significant digits.

A metal bar is in the xy-plane with one end at the origin. A force: is applied, where the vector from the origin is . Find the magnitude of the torque, in Nm, with respect to the origin produced by . Provide your answer to three significant figures. 

Freckles (F) is a trait that is dominant to not having freckles (f). On a separate chromosome, having a widow’s peak (W) is dominant over having a straight hairline (w). A woman who is heterozygous for both traits wants to have children with a man who is heterozygous for widow’s peak and homozygous recessive for the freckles trait. What percentage of their children will have a straight hairline and have freckles?
