A 46 kg ballerina stands on the tip of a single toe, with the cross-sectional area of 2.5 em'. What stress does the ballerina's toe experience ? HY 125 Recitation 9-10 Section: A) 1.8 x 10* Pa B) 1.8 MPa C) 1.8 x 10' N/m D) 5.5 x 10 7 Pa E) 1.8 N/ m- 9. A spring with constant * = 78 N/m is at the base of a frictionless, 50.0- inclined plane. A 0.50-kg block is pressed against the spring. compressing it 0.20 m from its equilibrium position. The block is then released. If the block is not attached to the spring, how far up the incline will it travel before it stops? A) 0.08 m B) 0. 16 m C) 0.32 m D) 0.64 m E) 1.Im 10. A professional basketball has a radius of 24.26 cm. How much force does it take to hold a basketball so that it is completely submerged in pure H.O. (Note: 1 1b is approximately 4.45 N and the density of H.o is 1000 kg/m') A) 58.2 1bs B) 100 lbs C) 132 lbs D) 144 lbs E) Not enough information has been provided
