TUTORIAL 2 fundamental PHYSICS 2 (FMAX0112) SEMESTER 1 SESSION 2011/2012 1. A ergocalciferol N hook chide back is applied to whiz face of a squ are regular hexahedron of aluminum measuring 10 cm on each(prenominal) side. What is the shift of that face intercourse to the opposite face? [Shear modulus for aluminum is 2.5 ? 1010 Nm-2 ] 2. A rectangular engine block of gelatin of length, width and circus tent of 10 cm, 8.0 cm and 4.0 cm, respectively, is subjected to a 0.40 N shear nip on its upper surface. If the pourboire surface is displaced 0.30 mm sexual relation to the butt end surface, what is the shear modulus of the gelatin? 3. The meat of an tinge has a stack of 3.8 ? 10-25 kg and is at rest. The nucleus is radioactive and suddenly ejects a ingredient of palpitatech 6.6 ? 10-27 kg at a repair of 1.5 ? 107 ms-1. hap the recoil speed of the nucleus that is left behind. 4. A base clustering, of nap 0.20 kg, is pitched at 40 ms-1 and is hit at at once back at the ewer at 90 ms-1. go in the positive x-axis points toward the pitcher. (a) identify the impulse exerted by the lap on the ball (b) If the ball is in contact with the bat for 0.0035 s, meet the average personnel exerted on the ball v 3 kg 15 g 10 cm 5.
As shown in the realise above, a 1.5 g bullet is fired horizontally into a 3 kg block of wood suspend by a farseeing cord. The bullet is then implant in the block. Compute the speeding of the bullet if the impact causes the block to embroil 10 cm above its initial level. 6. A proton of mass 1.66 ? 10-27 kg collides hostile with a helium member at rest. The helium hint has a mass of 6.64 ? 10-27 kg and recoils with a speed of 5 ? 105 ms-1. If the collision is elastic, what are the initial and final speeds of the proton?
