TUTORIAL 2 BASIC PHYSICS 2 (FMAX0112) SEMESTER 1 SESSION 2011/2012 1. A 500 N shear get to back is applied to one face of a dice of aluminum measuring 10 cm on individually side. What is the shift of that face relation back to the opposite face? [Shear modulus for aluminium is 2.5 ? 1010 Nm-2 ] 2. A rectangular block of gelatin of length, width and teetotum of 10 cm, 8.0 cm and 4.0 cm, respectively, is subjected to a 0.40 N shear jampack on its upper surface. If the top surface is displaced 0.30 mm relative to the butt end surface, what is the shear modulus of the gelatin? 3. The nitty-gritty of an jot has a stack of 3.8 ? 10-25 kg and is at rest. The nucleus is hot and suddenly ejects a particle of batch 6.6 ? 10-27 kg at a repair of 1.5 ? 107 ms-1. recollect the recoil speed of the nucleus that is left behind. 4. A base ball, of aggregative 0.20 kg, is pitched at 40 ms-1 and is hit at once back at the hummock at 90 ms-1. go in the positive x-axis points toward the pitcher. (a) Find 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 forcefulness exerted on the ball v 3 kg 15 g 10 cm 5.

As shown in the go out above, a 1.5 g bullet is fired horizontally into a 3 kg block of wood suspended by a long cord. The bullet is then embedded in the block. Compute the velocity of the bullet if the impact causes the block to hang back 10 cm above its sign level. 6. A proton of mass 1.66 ? 10-27 kg collides head-on with a helium atom at rest. The helium atom has a mass of 6.64 ? 10-27 kg and recoils with a spe ed of 5 ? 105 ms-1. If the collision is elas! tic, what are the initial and final speeds of the proton?
