Question

a bus statrs from rest accelerates in a straight line at a constant rate of 3 m/s2 for 8 seconds. calculate the distance travelled by the bus during this time interva

Answer 1

Answer:

The required distance travelled by the bus is 96 m.

Explanation:

Given :

Initial velocity, u = 0 m/s (initially at rest)

acceleration, a = 3 m/s²

time, t = 8 sec

To find :

the distance travelled by the bus during the time interval

Solution :

Second equation of motion :

$\longmapsto \bf S=ut+\dfrac{1}{2}at^2$  

Substituting the values,

$\sf S=0(8)+\dfrac{1}{2}(3)(8^2) \\\\ \sf S=\dfrac{1}{2}(3)(64) \\\\ \sf S=3 \times 32 \\\\ \sf S=96 \ m$

Therefore, the distance travelled by the bus during the time interval is 96 m
