Answer:
The average acceleration is 8.06 m/s².
Explanation:
It is given that,
Initial speed of the jet, u = 120 mph = 176 ft/s
Final velocity of the jet, v = 30 mph = 44 ft/s
Distance, d = 1800 ft
We need to find the average acceleration required of the airplane during braking. It can be calculated using third law of motion as :
a = acceleration
So, the average acceleration required of the airplane during braking is -8.06 ft/s². Hence, this is the required solution.
The radial force on the particle is given by the Lorentz force. They don't give you the velocity so you have to solve for it in terms of the radius and get them to cancel.
