Which of the following is equal to distance divided by time? a. displacement b. acceleration c. velocity d. speed

To find Speed you divide distance by time.

Reasoning:

Displacement is the change in an object's position from the origin.

To find Acceleration you use the equation a=v^2/r

To find Velocity you divide the distance by the time it takes to travel that distance, then you add your direction to it.

To find speed you use distance is over time

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

+15-35=-20

going in opposite directions
