Two objects have masses m and 5m, respectively. They both are placed side by side on a frictionless inclined plane and allowed to slide down from rest. a) It takes the heavier object 10 times longer to reach the bottom of the incline than the lighter object.
b) It takes the heavier object 5 times longer to reach the bottom of the incline than the lighter object.
c) It takes the lighter object 10 times longer to reach the bottom of the incline than the heavier object.
d) It takes the lighter object 5 times longer to reach the bottom of the incline than the heavier object.
e) The two objects reach the bottom of the incline at the same time.

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}.
