Answer:
1848.15J
Explanation:
KE =1/2 mv^2
Mass = 60kg, velocity =40km/h =11.11m/s
Hence
KE =30 x(11.1)^2 /2 = 1848.15J
Answer:
distance between the objects
masses of the objects
Explanation:
Gravitational force is a force of attraction that pulls two objects with masses together.
To best understand the concept of gravitational force, newton's law of universal gravitation provides a good insight. The law states that "every object in the universe attracts each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distances between them".
From the law, we see that gravitational force is dependent on the masses of the object and their distances.
