How does the skater's potential energy change as he moves down the ramp?

The skater's potential energy decreases. The skater's potential energy increases as he moves up the ramp, since the kinetic energy is being converted to potential energy. So as he moves down, it decreases.

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
