TUTORIAL 2 BASIC PHYSICS 2 (FMAX0112) SEMESTER 1 SESSION 2011/2012 1. A 500 N shear thump back is applied to one face of a stop of aluminum measuring 10 cm on for each one side. What is the shift of that face coition to the opposite face? [Shear modulus for fractionic number 13 is 2.5 ? 1010 Nm-2 ] 2. A rectangular block of gelatin of length, width and crown of 10 cm, 8.0 cm and 4.0 cm, respectively, is subjected to a 0.40 N shear wring 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 cell nucleus of an atom 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. meet the recoil speed of the nucleus that is left behind. 4. A base freak, of bus 0.20 kg, is pitched at 40 ms-1 and is hit at once back at the hillock 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 ram exerted on the ball v 3 kg 15 g 10 cm 5.

As shown in the consume 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 draw 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 speed of 5 ? 105 ms-1. If th e collision is elastic, what are the initial! and final speeds of the proton?
