Question

A particle starts from rest and moves with a uniform acceleration of 5m/s2

for 10s and then it moves with a constant
velocity for 4s. Later it slows down and comes to rest in 5s, as shown in the velocity time graph below for the motion
of an object.
What is the distance travelled during this period of acceleration?
a) 250m
b) 200m
c) 125m

Answer 1

Explanation:

As the question graph is not provided,

Distance travelled from t = 0 (rest) to t = 10 s => s = 250 m.

Distance travelled from t = 10 s to t = 14 s => s = 200 m.

Distance travelled from t = 14 s to t = 19 s => s = 125 m.
