A particle moves along a straight line. The distance × described in time t is given by the equation x= t3 volts. The acceleration at t=1 is initial velocity =c:
Correct answer: A. A=1
- A. A=1
- B. B=2
- C. C=3
- D. D=4
Explanation
They just made the question confusing In fact it's very simple We have to find the velocity Distance is given as x=t³ Where t=1 So x=1 We know velocity is x/t Putting x=1 And t=1 We get velocity as 1 Which is option A

About Acceleration
Acceleration measures the rate at which velocity changes with time, including changes in speed, direction or both. Work includes average and instantaneous acceleration, the relation a = Δv/Δt, uniform acceleration equations, and interpreting velocity time and displacement time graphs, with acceleration carefully distinguished from velocity.
