A car is stopped for a traffic signal. When the light turns green, the car accelerates, increasing its speed from zero to 5.27 m/s in 0.833 s. What linear impulse and average force does a 69.8 kg passenger in the car experience

See explanation

Explanation:

From Newton's law; the rate of change of momentum is proportional to the impressed force. Hence;

F.t = mv- mu

F= force

t= time

m= mass

V= final velocity

u = initial velocity

since u = 0, mv= 0

F= MV/t

F= 69.8 × 5.27/0.833

F= 442 N

Impulse = Ft= 442 × 0.833= 368 Ns
