A runner runs 2.0 km in 5.0 minutes and then takes 10.0 minutes to walk back to the starting point. A) What is the average velocity for the first 5.0 minutes? B) What is the
average velocity for the time spent walking? C) What is the average velocity for the
entire trip? D) What is the average speed for the entire trip? (All answers can be given
in km/min)

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
