Q. A 151-kg crate rests on the flatbed of a truck that moves at a speed of 11.00 m/s around an unbanked curve whose radius is 57m. The crate does not slip relative to truck. Obtain the magnitude of the static frictional force that the truck bed exerts on crate.

Q. A 110 ball and a 250 ball are related by a 38--long, massless, rigid rod. The balls rotate about their center of mass at 150 what is the speed of the 110 ball?
