Answer:
Explanation:
yes object can move through a distance and can have zero displacement
as displacement is the shortest distance between two points eg: if a person has moved a distance of 20 m and comes back to his original place by moving back 20m in such a case distance moved by the person is 40m but his displacement is 0 as shortest distance covered by him is 0 as he is in his original place
Yes, it is possible for a body to have traveled a distance yet have a displacement of zero.
Distance traveled by a body is the length of the path covered by it.
On the other hand displacement of a body is the shortest distance between the initial and the final point of a body.
When a body is traveling such that it ends at the point from where it started its journey, it covers a distance but the displacement of the body is zero.
So a body that has moved through a distance can have zero displacement.
Answer:
1962 W
Explanation:
P = W/t
P = F d cos theta / t
P = (500 kg) (9.81 m/s^2) (10 m) (cos 180) / 25 s <-- the displacement and the force act in opposite directions (but it doesn't matter because direction doesn't matter in this case)
P = 1962 W

<h2>Answer :</h2>
□ The Final velocity of body = 45 m/s
<h2>Given :</h2>
Initial velocity of body = 0 m/s
Acceleration of body = 3 m/s²
Time taken by body = 15 sec
<h2>To Calculate :</h2>
Final velocity of body = ?
<h2>How To Calculate ?</h2>
<h3>❒ </h3>
Here in this question we are provided that a body is in rest so it's initial velocity will be 0 m/s (because from rest), Acceleration of body is 3 m/s², and Time taken is also given which is 15 sec.
<h3>❒</h3>
To calculate the Final velocity of body we'll use the first equation of motion which says v = u + at
Where,
- v is the Final velocity in m/s.
- u is the Initial velocity in m/s.
- a is the Acceleration in m/s².
- t is the Time taken in second.
<h2>Calculation :</h2>
From first equation of motion
Hence, the Final velocity of body is 45 m/s.
