Using hookes law to find impulse

Click For Summary
SUMMARY

The discussion focuses on calculating the impulse delivered to a block during the first two seconds of oscillation using Hooke's Law. Given parameters include a maximum force (A) of 4N, a spring constant (k) of 12.3 N/m, and a mass of 4.9 kg. The impulse can be determined by integrating the force function over the specified time interval, utilizing the relationship between force and time derived from the oscillation equations. The key formula for impulse is F*Δt, where F varies with time and can be expressed as a sine or cosine function.

PREREQUISITES
  • Understanding of Hooke's Law and spring constants
  • Knowledge of oscillatory motion and periodic functions

Homework Statement


You are given a FORCE versus TIME graph, which shows oscillations with:

A= 4N at the max points
period is 4s
spring constant (k)= 12.3 N/m
mass of block exhibiting oscillation is 4.9 kg


How do you find the IMPULSE delivered to the block during the 1st 2 seconds of oscillation?

2. Homework Equations :
impulse=Δp
E=kx
x(t)= Acos(wt)
w=2∏f
W=deltaEk or F(D)



The Attempt at a Solution


x(t)=Acos(wt)

x(0)=4cos0=4N
x(2)=4N

I don't know how to connect this information

Welcome to PF, Captain!
Do you have the graph? It depends where it starts - is F=0 at time zero or what?
The usual impulse formula is F*Δt. Your F varies with time; can you integrate F*dt over the Δt?
 
Find the function F that defines force (it is a sine or cosine, from what you told). Integrate it over the time interval from 0 to 2 seconds.
