4) An aircraft has a landing velocity of 50 ms1 and decelerates uniformly at 10 ms2 to rest . Calculate:
(a) the time taken to slow down to this velocity
(b) the distance covered during the deceleration

physics 
bobpursley,
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.
