5 0

Answer:

Explanation:

a)  s = ½at²

a = 2s/t² = 2(1800)/12² = 25 m/s²

b) v = at = 25(12) = 300 m/s

c) first second  s = ½(25)1² = 12.5 m

twelfth second s = ½(25)(12² - 11²) = 287.5 m

Concerning the work done by a conservative force, which of the following statements, if any, are true? It can always be expresse
Vera_Pavlovna [14]

Answer:

It is independent of the path of the body and depends only on the starting and ending points.

Explanation:

In Physics we define a conservative force as a force that is independent of the path of the body and depends only on the starting and ending points.

For conservative forces we can write;

KEi + PEi = KEf +PEf

where;

KEi= initial kinetic energy

PEi= initial potential energy

KEf= final kinetic energy

PEf= final potential energy

This equation is known as the principle conservation of mechanical energy . It applies only to conservative forces where friction is negligible. The term KE + PE  is also known as the total mechanical energy of the system.

B) The student continues her investigation by loading the spring with different masses. The table shows her result.
liubo4ka [24]

Answer:

1) Id say the dependant is the distance

2) the force is calculated by dividing the mass by 100

Explanation:

the dependant variable is the variable you measure wich is in this case distance.

2. An example of a force applied against the direction of motion is: A) opening a door B)applying brakes suddenly to a moving ca
Blababa [14]

Answer:

Option(B),option(C) and Option(D) are the correct answer to the given question .

Explanation:

  • In the option(B) if we apply the force to stop the car. The motion and force of car is in the opposite direction .Suppose the person is moving the car to the straight and person immediately apply break the back wheel of the car is stop this means that  force and direction of motion is opposite that's why this is correct .
  • In the  option(C) the ball  and batsman hinting the ball is in the opposite direction .Suppose the ball is coming to the batsman to the right and it hits to the left its a opposite direction Therefore in this the force and direction of motion is opposite that's why this is correct .
  • In the option(D) if the person drawing water from a well there is always upward force is applied but there is always motion is there i.e downward force i,e mg.that's why  force and direction of motion is opposite that's why this is correct .
  • In the option(A) the force of opening the door of force and the motion is in the same direction therefore it is not the against the direction of motion that's why this option is incorrect .
