The angular frequency w is sqrt(k/m). Since m is reduced and the spring constant k remains the same, w is increased. If w goes up, the period goes down.
What about amplitude? The equilibrium position and the maximum displacement position of the Yhe amplitude remains unchanged. The maximum PE stays the same, and so does the maximumKE.
A box containing a pebble is attached to an ideal horizontal
spring and is oscillating on a friction-free air table. When the box
has reached its maximum distance from the equilibrium point, the
pebble is suddenly lifted out vertically without disturbing the box.
Will the following characteristics of the motion increase, decrease,
or remain the same in the subsequent motion of the box? Justify
each answer. (a) frequency; (b) period; (c) amplitude; (d) the maxi
mum kinetic energy of the box; (e) the maximum speed of the b
i believe f stays the same, speed is same, period decreases, Amp decreases, KE decreases. Am I right or wrong
