Two blocks are attached by a thin inextensible string over a frictionless, massless pulley. there is a frictional force between the block on the incline and the incline. the acceleration of gravity is 9.8 m/s 2 . 15 kg 14 kg µ t 1.2 m/s 0 m/s 2 34◦ calculate the magnitude of the frictional force acting on the block on the incline. answer in units of n.

Asatellite that goes around the earth once every 24 hours iscalled a geosynchronous satellite. if a geosynchronoussatellite is in an equatorial orbit, its position appearsstationary with respect to a ground station, and it is known as ageostationary satellite find the radius rof the orbit of a geosynchronous satellite that circles the earth.(note that ris measured from the center of the earth, not the surface.) you mayuse the following constants: the universal gravitational constant g is 6.67 \times 10^{-11}\; {\rm n \; m^2 / kg^2}. the mass of the earth is 5.98 \times 10^{24}\; {\rm kg}. the radius of the earth is 6.38 \times 10^{6}\; {\rm m}.
