First write down all the data given in the question and what to find. Use correct formula to calculate the unknown quantity. 

For example: if initial and final velocity and time taken is given and you have to find acceleration, then apply first equation of motion; v=u+at.

If initial and final velocity  and time taken is given and you have to find the distance travelled then firse find acceleration by using 1st equation of motion: v=u+at and after that apply 2nd equation of motion to calculate distance: s= ut+1/2at2

(3 X 3 = 9) CASE STUDY QUESTION 26. Ultrasounds can be used to detect cracks and flaws in metal blocks. Metallic components that are generally used in construction of big structures like buildings, machines and also scientific equipment. The cracks or holes inside metal blocks, which are invisible from outside, reduce the strength of the structure. Ultrasonic waves are allowed to pass through the metal block and detectors are used to detect the transmitted waves. If there is even a small defect, the ultrasound gets reflected back indicating the presence of flaw or defect. Clearly indicated in the figure Defect or flaw Ultrasound Detectors Metal Block (a) The transmitter sends an ultrasound wave of speed 5960m/s through a long steel bridge and a block reflects it back after 0.02s. how far the block in the metal bridge is from the transmitter. (b) With the above property of ultrasound waves, Can ultrasonic waves be used in the medical field? If so, how and give one use in the medical field to justify your answer? (c) Give two practical applications of reflection of sound waves?
