Question part points submissions used a car is stopped for a traffic signal. when the light turns green, the car accelerates, increasing its speed from 0 to 5.30 m/s in 0.812 s. (a) what is the magnitude of the linear impulse experienced by a 62.0-kg passenger in the car during the time the car accelerates? kg · m/s (b) what is the magnitude of the average total force experienced by a 62.0-kg passenger in the car during the time the car accelerates? n

(a) 328.6 kg m/s

The linear impulse experienced by the passenger in the car is equal to the change in momentum of the passenger:

where

m = 62.0 kg is the mass of the passenger

is the change in velocity of the car (and the passenger), which is

So, the linear impulse experienced by the passenger is

(b) 404.7 N

The linear impulse experienced by the passenger is also equal to the product between the average force and the time interval:

where in this case

is the linear impulse

is the time during which the force is applied

Solving the equation for F, we find the magnitude of the average force experienced by the passenger:
