Question

An airplane accelerates down a runway at 3.0 m/s/s for 10 s until it finally lifts off the ground.

Determine the velocity at take-off.

Answer 1

30 m/s

Step-by-step explanation:

Given:

v₀ = 0 m/s

a = 3.0 m/s²

t = 10 s

Find: v

v = at + v₀

v = (3.0 m/s²) (10 s) + 0 m/s

v = 30 m/s
