Answer 1

Explanation:

given :

• apple of mass = 0.15kg

• earth of mass = 6 x 10 kg

• earth radius = 6.4 x 10 m

• gravity constant = 6.67 x 10 Nm² kg-²

to find :

• apple of earth Acceleration = ?

• apple of earth Acceleration = ?

formula of acceleration is:

• g = GM/r²

solution :

• please check the attached file

thus :

• the acceleration of apple = 2.5 ×10 m/s
