Question

A boy moving by a bike with a velocity 5m/s accelerates for 5sec at the rate of 2m/s.Find its final velocity.​

Answer 1

Answer:

15m/s

Explanation:

According to the first equation of motion,

V = u+ at

V= 5 + 2*5

=5+10

=15m/s

Please mark this answer as the brainliest.

Answer 2

Here initial velocity, u= 5m/s

acceleration, a= 2m/s²

Time, t = 5sec

Therefore using the equation, v=u+at

v= 5+ 2 x 5

v= 15m/s

Therefore his final velocity is 5m/s.
