1. A 3600 jet touches down at 250 on the deck of an aircraft carrier and immediately deploys a parachute to slow itself down. If the plane comes to a stop in 180 , what is the average force of air on the parachute? Assume the parachute provides essentially all the stopping force.
2. Fnet= mass*acceleration, a=v/t, v=p/t
3. M=3600kg
v=250km/h
p=180
v=p/t 180m/25000m/h convert the kilometers to meters t=7.2e^-4*3600
t=2.592
250000m(1/3600sec)= 69.4 m/s
fnet=ma
m=3600
fnet=3600kg(69.4(m/s)/(2.592 s)= 96450N
i tried doing it but i keep on getting it wrong.
