A jumbo jet needs to reach a speed of 364 km/hr on the runway for takeoff. Assuming a constant acceleration and a
runway 1.5 km long, what minimum acceleration (in units of m/s2 ) from rest is required?

Answer :

Answer:

Diaplacement s=1.80km

Final velocity v=360km/h

It starts from rest. So, initial velocity u=0

We need to find the constant acceleration (a).

using the equation of motion v
