A person pushes a desk across the floor against friction and loud scraping noises. Identify all energy types in this scenario & a timeline how energy flows, transfers ,& what type of energy it ends with?

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

a, c, d, e are all applying about success strategies.

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
