Ball B (v) with a mass of 2.0 kg is rotating in an orbit of r = 0.8 m with a velocity = = 2.4 m / s. From this moment on, find the velocity of ball B at the moment when r is 0.5 m since the rope attached to it is pulled as shown in the figure with v, = 1.2m / s. Also calculate the work required to pull the rope.

SORU 2:
2.0 kg kütleli B topu (v), =
hızıyla r = 0.8 m yarıçaplı bir yörüngede
dönmektedir. Bu andan itibaren kendisine
r = 0.8m
B
bağlı ip v, = 1.2m/s hızı ile şekildeki gibi
çekildiğine göre r 0.5 m olduğu
andaki B topunun hızını bulunuz. Aynı
zamanda ipi çekmek için yapılması
gereken işi de hesaplayınız.
