)alex noticed that a metal door was not closing all the way on hot days, but closes all the way when it cools off at night. explain what is happening with the door during the day and at night using the words "kinetic energy" and "thermal energy".

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

no

explanation:

no i dont know how to solve this you should probably try to google the answer
