Question

When a body moving with an initial velocity of 30m/s is given an acceleration of 5m/s .what will be its final velocity after 4s ​

Answer 1

Answer:

Initial velocity (u) =30 m/sec

Acceleration (a) =5 m/sec^2

Time(t) =4 secs.

We know that,

v=u+at

or, v=30+5×4

or, v=30+20

or, v=50 m/sec.
