Question
A body moves from rest from a point A. It moves to another point B in 10 s, the motion being accelerated one and achieves a velocity 60 m/s at B. It then moves on to C with the uniform velocity for 20 s when it is immediately brought to rest. Draw a graph showing the complete motion and calculate the total distance travelled.
Solution
Given, a body from rest.
The above figure illustrates the motion of body at different points.
AB represents the accelerated part of motion.
BC represents the uniform motion.
At C, velocity of the body is abruptly made zero (point Q).
Distance travelled during the first 10 s is,
