SUMMARY

The impulse experienced by a 70kg person landing after a jump from a height of 5m can be calculated using the equation for impulse, I = Δp = FΔt, where I represents impulse, Δp is the change in momentum, F is the force, and Δt is the time duration of the force application. To determine the impulse, one must first calculate the momentum before landing, which is influenced by gravitational acceleration. This discussion emphasizes the importance of understanding the relationship between impulse and momentum in physics.

PREREQUISITES
  • Understanding of basic physics concepts, specifically impulse and momentum.
  • Knowledge of gravitational acceleration (approximately 9.81 m/s²).
  • Familiarity with the equations of motion for free fall.
  • Ability to perform calculations involving force and time duration.
NEXT STEPS
  • Study the derivation of the impulse-momentum theorem.
  • Learn how to calculate gravitational potential energy and its conversion to kinetic energy.
  • Explore real-world applications of impulse in sports and engineering.
  • Investigate the effects of varying landing surfaces on impulse experienced during jumps.
USEFUL FOR

Students preparing for physics exams, educators teaching mechanics, and anyone interested in the practical applications of impulse and momentum in real-life scenarios.

im reviewing for my final tomorrow, and there is a question that asks for the impulse experienced if a 70kg person lands on firm ground and stops after jumping from a height of 5m. what equation should i use to solve this?

Start with writing down the equation for impulse. Impulse= ?
 
i don't know the equation for impulse, that's my main problem :P
 
<br /> I = \Delta p = F\Delta t<br />

Where I is impulse, and p is momentum.

So impulse is a change in momentum, or the product of a force and the time period over which it acts.
