Question

a body starting from rest has an acceleration of 20 ms -2 the distance travelled by it in the 6th second will be
A) 1100m
B)11m
C)110m
D)100m

Answer 1

initial velocity, u = 0 m/s { since the body starts from rest }

acceleration, a = 20 m/s²

Distance travelled in 6 s = ?

We know,

h = ut + 1/2 at²

==> distance travelled = 0×6 + 1/2 × 20 × 36

==> distance travelled = 10 × 36

==> distance travelled = 360

Hence, the body will travel a distance of 360 m in 6 s.
