23. A car starts from rest and moves with constant acceleration of ( 2 , \textm/s^2 ) for 10 seconds. Then it moves with constant velocity for 20 seconds. Finally, it decelerates uniformly at ( 4 , \textm/s^2 ) to stop.
Calculate:
(i) Maximum velocity attained
(ii) Total distance covered
(iii) Total time of travel
24. A body of mass 5 kg is placed on a rough horizontal surface (( \mu = 0.4 )). A horizontal force of 30 N is applied.
(i) Will the body move?
(ii) If yes, find acceleration.
(iii) If no, find the frictional force.

25. A steel wire of length 2 m and diameter 1 mm is stretched by a force of 200 N. Given Young’s modulus of steel = ( 2.0 \times 10^11 , \textN/m^2 ), calculate:
(i) Stress
(ii) Strain
(iii) Extension in the wire
26. In a resonance tube experiment, the first resonance is obtained at a length of 16 cm and the second at 50 cm. The tuning fork frequency is 512 Hz.
