Momentum (x $10^3$ kg*m/s) 10.0 20.0 30.0 speed (m/s) Momentum as a function of Speed 6. Use the graph of momentum as a function of speed to determine the object's mass. [~1.08 x $10^3$ kg] You can choose any two points time (s) 5.0 10.0 15.0 y = mx + b slope p = mv + 0 mass = slope y int = 0 A 0.25 kg mass is attached to a 1.00 m length of string. The string completes a horizontal circle in 0.420 s. Calculate the a. speed of the mass. [15.0 m/s] b. magnitude of its momentum. [3.7 kg*m/s] m = 0.25 kg V = 2πr V = $\frac{\Delta d}{\Delta t}$ d = 6.2830 P = mv

Discussion of Code Modifications and Operational Differences Operational Differences: The modified code calculates frequency every 250 ms, which is four times per second. By multiplying the pulse count by 4, the code approximates the number of pulses per second. Advantages of Modifications: This setup balances accuracy with responsiveness by frequently updating the frequency reading. Possible Limitations: At higher frequencies, interrupt handling limitations could still cause missed pulses, impacting accuracy. For very high frequencies, a specialized frequency counter or dedicated hardware would provide better accuracy.
