What is Newton's law of universal gravitation?
2 answers:
Newton's law of universal gravitation, introduced by Sir Issac Newton, states that an object entices every other object in the universe with a force or pressure that is straightly proportional to the product of their masses and reversely proportional to the square of the distance between them.
In simple expression it is a law declaring that any two masses stimulate each other with a force equal to a persistent of gravitation multiplied by the outcome of the two masses and divided by the square of the distance across the space separating between the two objects or regions.

Answer:
90 m
Explanation:
Acceleration, where v and u are final and initial velocities respectively, t is the time taken
Substituting for a, 4 m/s for u and 10 s for t then
1*10=v-4
v=14 m/s
From kinematic equations
Making s the subject then
