Question

2. An airplane attains a velocity of 200 ms-1 in 30 s at the airstrip. Find its acceleration.​

Answer 1

Answer:

u=0m/s , v= 200m/s time taken to attain the velocity=30s

therefore, a=v-u/t=(200/30)m/s^2= 6.66m/s^2

Answer 2

Explanation:

here,

initial velocity (u)= 0 m/s

final velocity (v) = 200m/s

time = 30 s

so, acceleration= v- u divided by time

= 200- 0 divided by 30

= 6.66m/s2
