Question

Block M, with a mass of 1.00 kg is placed next to a spring on a frictionless surface. It is pushed to the left, compressing the spring by 5.0 cm until the center of the block reaches point P. The block is then released. When the center of the block is at point Q, the block leaves the spring. It moves along the frictionless surface past point S. Point R Is halfway between point Q and points S. Which of the following best describes the kinetic energies of the block at points P, Q, R. and S (in J)? K_P K_Q K_R K_S 0 3.13 3.13 3.13 0 3.13 6.61 7.03 0 3.13 7.03 7.03 0 3.13 7.56 7.56 0 7.56 7.56 7.56 Anna and Bob hold opposite ends of a 2.0 m long pole while standing on ice. Assume their mass of 50.0 kg and Bob has a mass of 80.0 kg. Anna

Explanation / Answer

option b is corrct

initially spped is zero so kinetic energy also is zero

and accelerations is high

then released from spring block gets more and more kinetic energy and acceleration decreases towards the mean position.

so option has increasing kinetic energy
