A car has an average speed of 89.0 km/h for one hour, then an average speed of 96.8 km/h for two hours during a three hour trip. What was the average speed for the three hour trip?

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

there are no atoms
