Answer:
Increases with increase in mass
Explanation:
gravity is proportional to mass and inversely proportional to the square of the distance between them
F = GMm/d²
A)After 3,5s -->v=v0+gt=21+(-9,8•3,5)=21+(-34,3)=-13,3m/s;
b)The maximum height that the orange reaches is h max=v0^2/2g=22,5m;v^2=sqrt(2gh)=>h=v^2/2g=9,025m.The height of the orange is H=h max-h=13,475m.;
c)The orange is traveling down.
Answer:
Explanation:
The law of gravitation has to be used in this question along with Newton's second law
Answer:
It acts perpendicular to the velocity and is directed toward the center of the circle.
Explanation:
For a force to make an object move in a circular motion, the force must act perpendicular to the velocity and directed toward the center of the circle of motion as shown in the attached image.
