Question

how long will it take for a body accelerating by 2m per second square to gain a velocity of 10 meter per second, starting from rest?

Answer 1

Heya!Here is your answer friend⏬
--------------------------------------------

Given that the body starts from rest,

Initial Velocity , u=0

Final Velocity , v = 10 m/s

Acceleration. , a=2ms-2

Time taken , t=?

Using the first equation of motion ,
$a = \frac{v - u}{t} \\ 2 = \frac{10 - 0}{t} \\ 2t = 10 \\ = > t = 5sec$
