An object is moving initially with a velocity of 5.6 m/s. After 3.1 s the object's velocity is – 2.7 m/s. What is the
object's average acceleration during this time?

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

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
