Sample Problems and Their Solutions (Based on Feb 2013 Paper)

Example 1: Mechanics

Question: A block of mass 2 kg slides down an inclined plane of length 5 m and inclination angle 30°. Find the acceleration of the block and the velocity at the bottom, assuming friction is negligible.

Solution:

• Step 1: Resolve component of gravity along the incline:

\( a = g \sin \theta = 9.8 \times \sin 30° = 9.8 \times 0.5 = 4.9\, \text{m/s}^2 \)

• Step 2: Use equations of motion:

• Initial velocity \( u = 0 \)
• Distance \( s = 5\, \text{m} \)

\( v^2 = u^2 + 2as \)

\( v^2 = 0 + 2 \times 4.9 \times 5 = 49 \)

\( v = \sqrt{49} = 7\, \text{m/s} \)

Answer: Acceleration \( 4.9\, \text{m/s}^2 \), velocity at bottom \( 7\, \text{m/s} \).

Example 2: Thermodynamics

Question: A copper calorimeter of mass 0.2 kg contains 0.5 kg of water at 80°C. The calorimeter and water are cooled to 30°C. Find the heat lost by water and calorimeter. Specific heat capacities: \( c_{Cu} = 0.385\, \text{kJ/kg°C} \), \( c_{water} = 4.186\, \text{kJ/kg°C} \).

Solution:

• Step 1: Heat lost by water:

\( Q_{water} = m_{water} \times c_{water} \times \Delta T = 0.5 \times 4.186 \times (80 - 30) \)

\( Q_{water} = 0.5 \times 4.186 \times 50 = 104.65\, \text{kJ} \)

• Step 2: Heat lost by calorimeter:

\( Q_{Cu} = m_{Cu} \times c_{Cu} \times \Delta T = 0.2 \times 0.385 \times 50 = 3.85\, \text{kJ} \)

Note: Since heat is conserved, the total heat lost by water and calorimeter should be approximately equal to the heat gained by surroundings, considering negligible heat exchange elsewhere.
