1)Is there any way to derive an expression for the mass of a satellite in an orbit??(adsbygoogle = window.adsbygoogle || []).push({});

2)A projectile is fired with a velocity of 10 m/s at an angle of 30 to the horizontal. When it reaches the maximum height,an object dropping 40 m above the projectile, collides with the projectile.Find the range

3)Two bodies of mass m1 and m2 are projected one after another at the same angle and the same velocity.Which will be projected further, considering the fact that m1 is heavier than m2.
