Question #178334

A 20-g wooden ball is set in horizontal motion using the same set-up used in the activity. The hanging mass is 100 g. The radius of the motion is supposed to be 60 cm however the string made a 100 angle above the horizontal during the actual motion. What is the magnitude of the velocity of the wooden ball?

FT=Fc,F_T=F_c,mhg=mbv2rcosθ,m_hg=\dfrac{m_bv^2}{rcos\theta},v=mhgrcosθmb,v=\sqrt{\dfrac{m_hgrcos\theta}{m_b}},v=0.1 kg9.8 ms20.6 mcos100.02 kg=5.38 ms.v=\sqrt{\dfrac{0.1\ kg\cdot9.8\ \dfrac{m}{s^2}\cdot0.6\ m\cdot cos10^{\circ}}{0.02\ kg}}=5.38\ \dfrac{m}{s}.
