Answer:
F = f from Newton’s first law.
Explanation:
since the desk is moved in a straight line at a constant speed, newton first law tell us that the two forces must be equal.
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. since the table has been set in motion by the 400 N force, it will remain in motion unless it is been acted upon by an external force, and this means that the 400 N must be equal to the frictional force for it to have been in motion in the first instance.
Answer:
it just pulls them at the same time
Explanation:
I think this solution is a supersaturated solution. This solution is called us such because the solute in this solution is more than the solvent can dissolve or the ammount of solute exceeds the solutbility of the solute in a particular solvent.
The velocity of the satellite will be 200 kmph.
Since the satellite is in deep space, and there is nothing to restrict the motion of the satellite (No atmosphere or no friction), therefore the stopping of engine will not affect the velocity of the satellite.
Therefore the velocity of the satellite after few minutes will be 200 kmph.
Answer:
<h2>
14.4 m</h2>
The distance covered by the body is <u>1</u><u>4</u><u>.</u><u>4</u><u> </u><u>m</u><u>.</u>
<u>Sol</u><u>ution</u><u>,</u>
Initial velocity(u)= 0 m/s( according to Question, the body starts from rest.that's why initial velocity(u) becomes zero.
Acceleration (a)= 0.2 m/s
Time (t):
Now,
Applying third equations of motion:
Thus, the distance covered by the body is 14.4 metre.

- When a certain object comes in motion from rest, in the case, initial velocity(u)= 0 m/s
- When a moving object comes in rest,in the case, final velocity(v)= 0 m/s
- If the object is moving with uniform velocity, in the case, (u=v)
- If any object is thrown vertically upward, in the case, acceleration (a)= -g
- When an object is falling from certain height, in the case, u= 0 m/s
- When an object is thrown vertically upwards in the case, final velocity at maximum height becomes 0.
