a) How long does it take an airplane to take off it needs to reach a speed on the ground of 350 km/h over a distance of 600 meters (assume the plane starts from rest)?​

Answer:

v2=u2+2asv2=u2+2as

where vv is the final velocity, uu the initial velocity, aa is acceleration and ss is the distance travelled.

So vv=350 km/hr = 350*1000/3600 m/s

uu=0 (start from rest)

ss = 600 m

so

a=v−u2sa=v−u2s

**uses calculator**

a=0.081m/s2
