U = 0

a = 3m/s²

t = 10s

v = u+at = 0 + 3*10 = 30 m/s

∴ It will gain 30m/s in 10s.

a = 3m/s²

t = 10s

v = u+at = 0 + 3*10 = 30 m/s

∴ It will gain 30m/s in 10s.

we are given two quantities. ....

a = 3m/s^2

time = 10 secs.

as we know that plane starts from rest position...... so...

=> u = 0.

there's a formula....

v = u + at

put the values....

v = 0+ ( 3 )( 10 )

v = 0+ 30

v = 30 m/s

and here's the answer.
