1. How much force is required to cause the object to move ? 2. Once moving, how much force is required to keep the object moving without slowing down?
3.What trends does this graph have?
4.Why is there a change needed in the force of friction?

a sonic boom is a loud boom that breaks the sound barrier

explanation:

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
