TUTORIAL 2 BASIC PHYSICS 2 (FMAX0112) SEMESTER 1 SESSION 2011/2012 1. A 500 N shear baffle back is applied to one face of a regular hexahedron of aluminum measuring 10 cm on separately side. What is the shift of that face comparative to the opposite face? [Shear modulus for aluminium is 2.5 ? 1010 Nm-2 ] 2. A rectangular block of gelatin of length, width and height of 10 cm, 8.0 cm and 4.0 cm, respectively, is subjected to a 0.40 N shear tug 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 nub 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. envision the recoil speed of the nucleus that is left behind. 4. A base bunch, of surge 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 pitch er. (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 labour exerted on the ball v 3 kg 15 g 10 cm 5.

As shown in the have 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 cross 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 in! itial and final speeds of the proton?
