Why the motion of a satellite around a planet cannot be taken as S.H.M?

An artificial satellite is revolving around a planet fo mass M and radius R, in a circular orbit of radius r. From Kepler's third law about te period fo a satellite around a common central bdy, square of the period of revolution T is proportional to the cube of the radius of the orbit r. Show usingn dimensional analysis, that T = k/R sqrt((r^3)/(g)) , where k is a dimensionless constant and g is acceleration due to gravity.

The period of a satellite in a circular orbit around a planet is independent of

A boy throws a ball in air at 60^@ to the horizontal along a road with a speed of 10 m/s (36km/h). Another boy sitting in a passing by car observer the ball. Sketch the motion of the ball as observed by the boy in the car,if car has a speed of (18km/h). Give explanation to support your diagram.
