A particle of unit mass undergoes one-dimensional motion such that its velocity varies according to
where and n are constants and x is the position of the particle. The acceleration of the particle as a function of x, is given by:
As we learnt in
Acceleration -
Rate of change of velocity with time.
For: a=change in velocity / change in time
- wherein
Eg. A car starting from rest accelerates uniformly to a speed of 75 m/s in 12 seconds. What is car’s acceleration ?
0

?
a = 6.25 m/s2
