Velocity of a Particle with Given Acceleration


Given Information:


  • Acceleration of a particle, a = 3t^2 2t^2 m/s²

  • Initial velocity of a particle, u = 2 m/s

  • Time, t = 2 seconds



Calculating Velocity:

Velocity of a particle can be calculated by integrating the acceleration function with respect to time.

∫a dt = ∫(3t^2 + 2t^2) dt

∫a dt = ∫5t^2 dt

∫a dt = (5t^3)/3 + C

where C is the constant of integration.

Using the initial condition, we can find the value of C.

At t=0, v=u=2 m/s

(5(0)^3)/3 + C = 2

C = 2

Therefore, the velocity function becomes:

v = (5t^3)/3 + 2


Calculating Velocity at t=2 seconds:

Substituting the value of t=2 seconds in the velocity function, we get:

v = (5(2)^3)/3 + 2 = 46.67 m/s


Conclusion:

The velocity of the particle at the end of 2 seconds is 46.67 m/s.
