Question

a body moves from rest and attains a speed of 15m/s in 0.25minutes.find the acceleration​

Answer 1

Answer:

Acceleration= 1 m/s^2

Explanation:

Time(t) = 0.25 min = 0.25*60 sec

Speed(s) = 15 m/s

Acceleration = speed / Time

Acceleration = 15 / 0.25*60

Acceleration = 1 m/s^2

Answer 2

Answer:

answer is 1$m/s^{2}$

Explanation:

u=0 m/s

v= 15m/s

t=0.25min or 15 sec

accerleration = v-u/t

a=15-0/15

a= 15/15

a=1 $m/s^{2}$

hope it helps you to understand...
