Question

Please hurry

Starting from rest, this airliner accelerates at 2.4m/s2 for 32 seconds before leaving the ground. Calculate its velocity at liftoff.

Answer 1

The velocity will be "76.8 m/s".

Step-by-step explanation:

The given values are:

Acceleration,

a = 2.4 m/s²

Time,

t = 32 seconds

By equation of motion,

⇒
`v=u+at`

On substituting the values, we get

⇒
`=0+2.4* 32`

⇒
`=0+76.8`

⇒
`=76.8 \ m/s`
