Final answer:
To calculate the force exerted by an airbag on a 75 kg passenger brought to rest in 0.3 seconds from a speed of 23 m/s, the formula for average force F = (m × Δv) / Δt can be used.
Step-by-step explanation:
The question requires an understanding of physics concepts related to motion, particularly the calculation of average force exerted on a passenger during a car collision. When a car moving at a certain velocity comes to a stop, the deceleration experienced by the passengers can be used to calculate the force applied. To find the force exerted by the airbag on a 75 kg passenger brought to rest in 0.3 seconds, we use the formula:
F = (m × Δv) / Δt,
where F is the average force, m is the mass of the passenger, Δv is the change in velocity (initial velocity minus final velocity), and Δt is the time it takes for the change to occur. Given that the car was initially moving at 23 m/s and the final velocity is 0 m/s, the force can be computed.
