Math Problem Statement

The following data gives the velocity of a particle for 12 seconds at an interval of 3 seconds. Find the initial acceleration using the entire data.

Solution

To solve the problem of finding the initial acceleration using the given data, we can employ the finite difference method or any suitable approach for derivative approximation. Here's the approach:

  1. Identify the formula for acceleration:

    • Acceleration is the time rate of change of velocity: a(t)=dvdta(t) = \frac{dv}{dt}
  2. Use the given velocity data at regular intervals of time:

    • Time intervals: Δt=3seconds\Delta t = 3 \, \text{seconds}.
    • Initial time t=0t = 0: Velocity is 0m/s0 \, \text{m/s}.
  3. Calculate the approximate acceleration:

    • Use the formula for the forward difference approximation at t=0t = 0: a0=v1v0t1t0a_0 = \frac{v_1 - v_0}{t_1 - t_0} Here: v1=127m/s,v0=0m/s,t1=3s,t0=0s.v_1 = 127 \, \text{m/s}, \, v_0 = 0 \, \text{m/s}, \, t_1 = 3 \, \text{s}, \, t_0 = 0 \, \text{s}.
  4. Substitute the values: a0=127030=127342.33m/s2.a_0 = \frac{127 - 0}{3 - 0} = \frac{127}{3} \approx 42.33 \, \text{m/s}^2.

  5. Verify using central difference (if applicable):

    • Central difference gives a more accurate approximation of acceleration at points other than the boundary. However, since this is the initial acceleration, forward difference suffices.

Result:

The initial acceleration of the particle is approximately 42.33 m/s².

Let me know if you would like further details or calculations for acceleration at other points.


Questions for further exploration:

  1. How would the result change if smaller time intervals were provided?
  2. Can we calculate the average acceleration over the entire time range?
  3. How is the central difference method for derivative approximation different from forward difference?
  4. What are the potential errors in numerical differentiation using finite differences?
  5. How could this analysis be extended to find displacement using velocity data?

Tip: For smoother results, numerical differentiation can be improved by using smaller time intervals or higher-order approximation methods.
