Answer:
Explanation:
According to Newton's Second Law of Motion, force is the product of mass and acceleration.
The mass of the stone is 0.2 kilograms and the acceleration is 10.0 meters per square second.
Substitute the values into the formula.
Multiply.
Convert the units.
The force is <u>2 Newtons.</u>
To solve this problem we will apply the concepts related to the momentum.
This is defined as the product between the change in velocity and the mass of the object, that is
Where,
m = mass
Final velocity
Initial velocity
Our values are given as,
m = 14kg
= 11m/s
<em>the negative Symbol implies that the direction is opposite to the initial one and therefore there is also a change in the sense of magnitude</em>
The negative symbol indicates that the momentum has a direction opposite to that of the initial velocity. Or failing that, it has the same direction of the final speed
