How many pounds of pressure does a 25 pound baby weigh in a head on collision when the car is traveling at 25 miles per hour. (and hits a stationary object)

To calculate the pounds of pressure exerted by a 25-pound baby in a head-on collision, we need to use the concept of force. Force is defined as the product of mass and acceleration. Here are the steps to calculate the pounds of pressure:

1. Convert the baby's weight from pounds to mass in pounds-mass:
Since weight is the force on an object due to gravity, we can convert 25 pounds to mass using the acceleration due to gravity (approximately 32.17 ft/s² or 9.81 m/s²).
Divide the weight (25 pounds) by the acceleration due to gravity to get the mass:
Mass = Weight / Acceleration due to gravity

2. Convert the car's speed from miles per hour to meters per second:
To ensure consistency, convert the car's speed from miles per hour (mph) to meters per second (m/s). The conversion factor is 0.44704 m/s per mph.

3. Determine the acceleration:
In a head-on collision when a car hits a stationary object, we assume the initial speed of the baby is zero, and it reaches the final speed of the car during the collision. The change in velocity is the car's speed.
Acceleration = Change in velocity / Time taken

4. Calculate the time taken:
To calculate time, we need to know the distance traveled during the collision. As this information is not given, we cannot calculate the exact time taken. However, assuming a typical collision duration of 0.1 seconds, we can use this duration as an example.

5. Calculate the acceleration and force experienced by the baby during the collision:
The acceleration can be calculated using the formula a = Δv / Δt, where a is acceleration, Δv is the change in velocity, and Δt is the time taken.
Force = Mass × Acceleration

Finally, it is important to note that the calculated pounds of pressure obtained using the above steps provide an estimate and may not accurately represent the exact forces at play in a real-world collision scenario with varying factors.
