As shown in the figure below. April enters a race. She runs leftward 100 m to her horse, then she rides 500 m to her truck then she drives 1000 m in a total time of 120 s.

What is April's average velocity over the 120 s period?

What is April's average speed over the 120 s period?

it has to be b, about 97 percent.

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
