4) An aircraft has a landing velocity of 50 ms-1 and decelerates uniformly at 10 ms-2 to rest . Calculate:
(a) the time taken to slow down to this velocity
(b) the distance covered during the deceleration
formulas you can use:
vf=vi+at a is given as -10m/s^2
solve for time
Vf^2=Vi^2+2ad solve for distance.
