Tangential speed is constant, so only the centripetal acceleration counts.
(centripetal acceleration) = (velocity^2)/radius
so...
(c.a.) = (80^2)/750
= 6400/750 = 8.53333... m/s^2
Answer = 8.53 m/s^2

From what height should a car be dropped to gain the same kinetic energy it would have if it were moving horizontally at 95 km/hr?
