The jet fighter's acceleration at the highest point is 17.56 ft/s²
The jet fighter's acceleration at the lowest point is 35.12 ft/s²
The given parameters;
radius of the circular path, r = 1200 ft
constant velocity, v = 140 mi/h = 205.3 ft/s
The formula for centripetal acceleration in a circular path is given as;
[tex]a_c = \frac{v^2}{r}[/tex]
The jet fighter's acceleration at the highest point is calculated as;
h = 2r = 2 x 1200 ft = 2,400 ft
[tex]a_c = \frac{v^2}{r} \\\\a_c = \frac{(205.3)^2}{2400} \\\\a_c = 17.56 \ ft/s^2[/tex]
The jet fighter's acceleration at the lowest point is calculated as;
h = r = 1,200 ft
[tex]a_c = \frac{v^2}{r} \\\\a_c = \frac{(205.3)^2}{1200} \\\\a_c = 35.12\ ft/s^2[/tex]
