Question

given that the total distance travelled is 4 km and that the initial deceleration is 4m/s2, find :
(a) the value of V
(b) the value of T

Answer 1

v sq=u sq +2as...(1)

so v sq=0+ 2*4*4000

v sq=32000

v =178.88............answer

and

v=u - at

178.88=0+4t

so

t=178.88/4

= 44.72 sec.........answer
