TUTORIAL 2 BASIC PHYSICS 2 (FMAX0112) SEMESTER 1 SESSION 2011/2012 1. A 500 N shear cram back is applied to one face of a stop of aluminum measuring 10 cm on apiece side. What is the shift of that face congenator to the opposite face? [Shear modulus for instalmentic number 13 is 2.5 ? 1010 Nm-2 ] 2. A rectangular block of gelatin of length, width and summit of 10 cm, 8.0 cm and 4.0 cm, respectively, is subjected to a 0.40 N shear reap 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 inwardness of an atom has a stack of 3.8 ? 10-25 kg and is at rest. The nucleus is radioactive and suddenly ejects a particle of batch 6.6 ? 10-27 kg at a repair of 1.5 ? 107 ms-1. detect the recoil speed of the nucleus that is left behind. 4. A base hunk, of mussiness 0.20 kg, is pitched at 40 ms-1 and is hit at once back at the pitcher at 90 ms-1. go in the positive x-axis points toward t he 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 suck exerted on the ball v 3 kg 15 g 10 cm 5.

As shown in the gather in 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 swing 10 cm above its initial 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 the collision is elastic, what ! are the initial and final speeds of the proton?
