Josh is cutting the grass with a push mower across horizontal ground! He pushes with a force of 52 N to the left, but downwards at an angle of 40º below the horizontal. There is a small
coefficient of friction of 0.20. The mower has a mass of 8.4 kg. Determine the force of friction
and the acceleration on the mower.

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}.
