Question

a boy starts from rest and acquires a velocity 10m/s in 2s.find the acceleration​

Answer 1

Answer:

5 m/s²

Explanation:

v=u+at

10=0+a*2

so, a=10/2=5

so, acceleration =5 m/s²

hope it will help you.

please mark me as brainliest answer.

Answer 2

Explanation:

Now as boy starts from rest so u=0m/s

v=10m/s

t(time) = 2 sec

Now we know acceleration → a=v-u/t

→a = 10-0/2

→ a= 10/2 = 5 m/s²

a=5 m/s² → Answer!
