A) 20 m
<h3>What is called magnitude of displacement?</h3>
The magnitude of displacement is defined as the shortest distance between the initial and final position of the object.
For a particle in motion, the magnitude is either less than or equal to the distance travelled.
Also,
Velocity is simply defined as the rate of change of displacement with time.
Mathematically, it can be expressed as:
Velocity = displacement / time
According to the question,
The following data were obtained:
Time = 5 s
Velocity = 4 m/s
Displacement =?
Velocity = displacement / time
4 = d / 5
D = 4 × 5
D= 20 m
Hence,
20 m is the magnitude of the displacement of the object after it travelled for five seconds.

The answer is C. Potential energy
(I learned this in class recently)
A rotation motion is a motion that takes place around a fixed axis.
Like gears turning on each other.
Answer:
We conclude that the force on the bag is 500 N.
Explanation:
Given
- Acceleration a = 0.5 m/s²
To determine
Force F = ?
We know that when a force is applied to a body, it produces acceleration.
<u>Important Tip: </u>
- We can determine the force on the bag using the formula F = ma
Using the formula
where
- is the force
- is the mass
- is the acceleration
now substitute m = 1000, and a = 0.5 m/s² in the formula
N
Therefore, we conclude that the force on the bag is 500 N.
