What can be defined as the rate at which velocity changes

acceleration

Explanation:

The rate at which velocity changes is the definition of the physical quantity called acceleration, and it is given by the formula:

where is the time that took to change from the initial velocity to the final velocity

The rate at which velocity changes can be defined as acceleration or average acceleration.

Explanation:

The acceleration is defined as the rate of change of velocity with respect to time. So, the change in velocity from the initial velocity at different time intervals will help to attain the acceleration attained by the object.

where,

– final and initial velocities, – time  

If the change in velocity is constant for same time interval, then the acceleration will be constant for that object. So, an object can attain uniform acceleration when the velocity changes uniformly with 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
