Question

The formula for the time i taken by a
body travelling at a uniform acceleration
is given by
t=1/a (√a²+2As -u)
Where a is the uniform acceleration in
m/s?, u is the initial velocity in m/s and S
is the distance travelled in m.
(a) Show that S = { ar? + ut.
S
(b) Find S when u = 20 m/s,
a=9.8 m/s2 and 1 = 4 sec.​
