Answer:
time= 8 sec.
Step-by-step explanation:
A body starts from rest and move with uniform acceleration of 4 m/sec²
that means,
initial velocity (u) =0 m/sec
acceleration (a) =4 m/sec²
distance (s) =128 m
According to distance-time equation,
S = ut + 1/2 at²
128=0×t + 1/2 ×4 ×t²
128 = 0+2t²
t² =128/2
t²=64
t=8 sec.
it will take 8 sec. to cover a distance of 128 m.
