Answer:
The work done on the box is 80 J.
Explanation:
Given that,
Weight of box = 40 N
Distance = 2 meter
We need to calculate the work done
Using formula of work done
Where, x = distance
mg = weight
Put the value into the formula
Hence, The work done on the box is 80 J.

Explanation:
Assuming the initial point P1 of this vector is at the origin:
P1=(X1,Y1)=(0,0)
And knowing the other point is P2=(X2,Y2)=(19.5,28.4)
We can find the magnitude and direction of this vector, taking into account a vector has a initial and a final point, with an x-component and a y-component.
For the magnitude we will use the formula to calculate the distance between two points:
(1)
(2)
(3)
(4) This is the magnitude of the vector
For the direction, which is the measure of the angle the vector makes with a horizontal line, we will use the following formula:
(5)
(6)
(7)
Finding :
(8)
(9) This is the direction of the vector
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.
- m= 0.2 kg
- a= 10.0 m/s²
Substitute the values into the formula.
Multiply.
Convert the units.
- 1 kilogram meter per square second (kg*m/s²) is equal to 1 Newton (N)
- Our answer of 2 kg*m/s² is equal to 2 N
The force is <u>2 Newtons.</u>
