Question

Find the impulse produce by the force F= 5t-1N from t= 0s to t= 3s??

Answer 1

Answer:

19.5 N sec .

Explanation:

Given :

F = 5 t -  1 N  from t = 0 to t = 3 .

We have find Impulse .

We know :

Impulse = Force × Time

or

Impulse ( I ) = ∫ F d t

$\displaystyle{I=\int\limits^3_0 {5t-1} \, dt }}\\\\\\\displaystyle{I=\left[5t^2/2-t\right]^3_0}}\\\\\\\displaystyle{I=5\times3^2/2-0-3-0}\\\\\\\displaystyle{I=22.5-3}\\\\\\\displaystyle{I=19.5 \ N \ sec }$

Hence we get value of Impulse .
