Question

The velocity-time relation of an electron starting
from rest is given by u.-ktwhere k=2m/s.
The distance traversed in 3 sec is :-​

Answer 1

Answer:

The correct question is:

The velocity time relation of an electron starting from rest is given by u=kt where k = 2 m/s². What is the distance traversed in 3 seconds?

We know that Distance = Speed × Time

According to the relation given,

• u = kt
• k = 2m/s²

⇒ u = 2 × t = 2t m/s

It is given that we have to identify the distance travelled in 3 seconds.

⇒ t = 3

⇒ u = 2 × 3 = 6 m/s

Now we know the speed and the time. Hence substituting in the distance formula we get,

⇒ Distance = Speed × Time

⇒ Distance = 6 m/s × 3 sec

⇒ Distance = 18 m

Hence the distance traversed in 3 seconds is 18 m.
