A body is moving with a velocity of 10m/s.If the motion is uniform, What will be the velocity after 10s?Is the velocity a vector or scalar quantity? About the author Cora
Given : Initial velocity = 10 m/s Time taken = 10s To find : Velocity after 10s Solution : As given in the question that the body is in uniform motion. So the acceleration will be zero [tex]a = \frac{(v – u)}{t} \\ \\ 0 = \frac{(v – 10)}{10} \\ \\ 0 \times 10 = v – 10 \\ 0 = v – 10 \\ v = 10 \: m {s}^{ – 1} [/tex] So, the velocity after 10s is 10 m/s Reply
Given :
Initial velocity = 10 m/s
Time taken = 10s
To find :
Velocity after 10s
Solution :
As given in the question that the body is in uniform motion. So the acceleration will be zero
[tex]a = \frac{(v – u)}{t} \\ \\ 0 = \frac{(v – 10)}{10} \\ \\ 0 \times 10 = v – 10 \\ 0 = v – 10 \\ v = 10 \: m {s}^{ – 1} [/tex]
So, the velocity after 10s is 10 m/s
Answer:
Correct answer is 10m/s.
