Question

A bus starting from rest acceleration in a straight line at a constant rate 3m/s2 for 8 seconds .Calculate the distance travelled by the bus

Answer 1

Answer. Acceleration = 3m/s

initial velocity =0 (as it is starting from rest )

time taken =8 seconds

distance (s) =?

To find we will use equation of motion

s = ut + 1/2at×t

s =0×8 +1/2×3×8×8

s= 1/2×3×64

s = 96 metres

Answer 2

________________________________________

Here,

• u = 0 ; a = $\rm 3 \: {ms}^{ - 2}$ ; t = 8s ; S = ?

Using,

• $\rm \implies{S = ut + \frac{1}{2} {at}^{2},we \: get}$

• $\rm \implies{S = 0 + \frac{1}{2} \times 3 {ms}^{ - 2} \times 64 {s}^{2} }$

• $\rm \implies </u></strong><strong><u>\red{ = 96m</u></strong><strong><u>}</u></strong><strong><u>$
