Start with writing down the equation for impulse. Impulse= ?phintastic said: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?
To calculate impulse, you need to know the mass of the person (in kilograms) and the vertical distance they jump (in meters). Then, you can use the formula: Impulse = mass x change in velocity. In this case, the change in velocity would be the velocity at which the person lands after jumping, since they start at 0 velocity.
The unit of measurement for impulse is kilogram meter per second (kg * m/s).
The mass of the person is important because it affects the amount of force required to change their velocity. The greater the mass, the greater the force needed to change their velocity, and thus the greater the impulse experienced.
The height of the jump directly affects the impulse experienced by a person. The higher the jump, the greater the change in velocity and therefore the greater the impulse experienced. In the formula for impulse, the change in velocity is multiplied by the mass, so a higher jump with the same mass will result in a greater impulse.
Yes, impulse can be negative. This occurs when the change in velocity is negative, meaning the person's velocity decreases instead of increasing. For example, if a person jumps and then immediately falls back down, their change in velocity would be negative and so would the impulse experienced.
