Final answer:
To determine the force of a car at impact, you need to know the car's velocity before the impact and the duration of the impact. This information can be obtained from video footage, crash test data, or calculations from distance and time data. Once these are known, they can be plugged into the formula for impact force to calculate the force.
Step-by-step explanation:
To calculate the force of the car at impact using the formula for impact force, you need some specific data in addition to the mass and duration of impact. The main data you would need is the velocity of the car before the impact and the duration of the impact.
The velocity can be calculated from data on the distance traveled and the time it took, or from readings on the car's speedometer if it's available. The duration of the impact would typically be a very short time period, and can be estimated based on video footage, or from data provided by crash test experiments.
The formula for impact force is f = mv/t, where f is force, m is mass, v is velocity, and t is the duration of impact. Once you have all these data, you can substitute them into the formula to calculate the force of impact.
