A spring (k= 500 N/m) has been compressed by 15.0 cm with a mass M (450-g) at its one end. When the block is released on a horizontal ground of μ = 0.25, (a) What would be the block speed when the spring is fully relaxed (point A)? (b) After the block is detached from the spring at point A, it moves up a frictionless vertical circular track of radius R = 25.0 cm. Would the block be able to reach the top of the circular track (point B)? If it would, find its speed at B. If not, state your reason and condition needed for it to reach point B.

Transcribed Image Text:A spring (k = 500 N/m) has been compressed by 15.0 cm with a mass M (450-g) at its one
end. When the block is released on a horizontal ground of μ = 0.25,
(a) What would be the block speed when the spring is fully relaxed (point A)?
(b) After the block is detached from the spring at point A, it moves up a frictionless vertical
circular track of radius R = 25.0 cm. Would the block be able to reach the top of the
circular track (point B)? If it would, find its speed at B. If not, state your reason and
condition needed for it to reach point B.
