Questions
The position of a particle moving along the x-axis at certain times is given below :
| t (s) | 0 | 1 | 2 | 3 |
| x (m) | –2 | 0 | 6 | 16 |
Which of the following describes the motion correctly
a
Uniform, accelerated
b
Uniform, decelerated
c
Non-uniform, accelerated
d
There is not enough data for generalization
detailed solution
Correct option is C
from the given data , instant velocity is estimated using two successive readings to evaluate the consistency Instantaneous velocity v=ΔxΔt By using the data from the table v1=0−(−2)1=2m/s. v2=6−01=6 m/s v3=16−61=10 m/s hence motion is non-uniform but acceleratedTalk to our academic expert!
