Question

4. An aeroplane lands at 216 km/hr and stops after covering a runway of 2 km. Calculate the
acceleration and the time, in which it comes to rest.​

Answer 1

Answer:

Explanation:

Using equation (1) with given values, 0^2-(216)^2(km/h)^2=2 a (2 km). Therefore, a=-11664 km/h^2 =-11,664(1000 m)/(3600s)^2=-0.9 m/s^2.
