The following bar graph (Figure) represents the heights (in cm) of 50 students of Class XI of a particular school. Study the graph and answer the following questions: What percentage of the total number of students have their heights more than 149 cm? How many students in the class are in the range of maximum height of the class? The school wants to provide a particular type of tonic to each student below the height of 150cm to improve his height. If the cost of the tonic for each student comes out to be Rs. 55, how much amount of money is required? How many students are in the range of shortest height of the class? State whether true or false: There are 9 students in the class whose heights are in the range of 155-159 cm. Maximum height (in cm) of a student in the class is 17. There are 29 students in the class whose heights are in the range of 145-154 cm. Minimum height (in cm) of a student is the class is in the range of 140-144cms. The number of students in the class having their heights less than 150cm is 12. There are 14 students each of whom has height more than 154 cm.

A pan of mass m = 1.5 kg and a block of mass M = 3 kg are connected to each other by a light inextensible string, passing over a light pulley as shown in Fig. Initially, the block is resting on a horizontal floor. A ball of mass m_0 = 0.5 kg collides with the pan at a speed v_0= 20 m//s . Consider this instant of collision as t = 0 . Assume collision to be perfectly inelastic. Now, Fig. answer the following questions based on the above information. Find the time t at which the block strikes the floor for the first time
