Answer:
The gravitational force between two objects depends only on their masses.
i think sorry if its wrong!!
Explanation:
Answer:
22 m/s
Explanation:
PEf +KEf =PE0 +KE0 →PE0 −PEf =KEf
−mgΔy= 1 mv2 →v= −2gΔy = −2(9.8 m/s2)(−25 m)=22 m/s
Answer:
Suppose any object with mass in our planet.
The object will be affected by the gravitational force, that pulls the object down. Now, a table in your dining room is also affected by this force, but the table is in a surface (the ground) and it does not move.
We know that if an object does not move, then the net force acting on it is equal to zero, this means that there is a force equal and opposite ot the gravitational force.
This force is the normal force, that the ground applies on the table. This force comes as a "response" to the table pushing the ground (By 3rd Newton's law).
So two forces that are always equal and opposite are the forces caused by this law.
Answer:
1) The net force is 5 N. The box is accelerating 10 m/s
2) The net force is 6.986 N. It is accelerating. Normal Force is 16.986
Explanation:
1) 20 N forward - 15 N backwards = a net force of 5 N
Acceleration: Acceleration = Net Force * Mass ( derived from Force = mass * acceleration).
a = 5 N / 2 kg
a= 2.5 m/s^2
2)
Answer:
What is the magnitude of the player 's displacement? A baseball "diamond" is a square, each side of length 27.4 m, with home plate and if each length of the base is 27.4 m, and the baseball player ran to third base,Then, the baseball player is 27.4 feet away from home plate (where he started)below the horizontal.
