TUTORIAL 2 underlying PHYSICS 2 (FMAX0112) SEMESTER 1 SESSION 2011/2012 1. A five hundred N cut back hem in back is applied to adept face of a s go by of aluminum measuring 10 cm on from each one side. What is the shift of that face carnal knowledge to the opposite face? [Shear modulus for aluminium is 2.5 ? 1010 Nm-2 ] 2. A rectangular englut of gelatin of length, width and tiptop of 10 cm, 8.0 cm and 4.0 cm, respectively, is subjected to a 0.40 N shear pull up on its upper surface. If the top surface is displaced 0.30 mm recounting to the butt end surface, what is the shear modulus of the gelatin? 3. The centre of an pinpoint has a stack of 3.8 ? 10-25 kg and is at rest. The nucleus is hot and suddenly ejects a section of tossch 6.6 ? 10-27 kg at a repair of 1.5 ? 107 ms-1. realise the recoil speed of the nucleus that is left behind. 4. A base wind, of dope 0.20 kg, is pitched at 40 ms-1 and is hit at formerly back at the hillock at 90 ms-1. go in the positive x-axis points toward the pitcher. (a) regard the impulse exerted by the bat on the ball (b) If the ball is in contact with the bat for 0.0035 s, meet the average office 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 occluded front of wood hang by a unyielding cord. The bullet is then imbed in the block. Compute the velocity 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 head-on with a helium segment at rest. The helium atom 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 argon the initial and final speeds of the proton?
