    5 years ago by srinjay ayan
    Ans 1 ->
    yes but you need practice from books also... first make sure you are confident with each and every question of HC Verma(including short answers and mcqs) then go for DC Pandey and IE Irodov. After this you can go for FIITJEE grand masters package. This will enough to fetch you a 2 digit or even 1 digit rank....but make sure you focus on maths and chemistry also. All the best!

    44. An aeroplane moving horizontally with a speed of 180 km/hr drops a food packet while flying at height of 490m the horizontal range of packet is ???
    7 years ago by roma yadav
    Ans 1 ->
    Converting The speed of the aeroplane into m/s by multiplying them with 18/5. we Get 180 * 18/5 = 648 horizontal velocity is 648m/s The height of the aeroplane from the ground is 490m. (i.e 490 = 1/2 *g *(t*t)) 490=1/2*10*(t*t) we get t=root over 98 the distance travelled horizontally in root over 98 second is = root over 98 * 648 (i.e the horizontal range)

    yes you can do it also... but to save time we first calculated the unit vectors and then found the angle between these... in many cases this method will help however here solution length will be same...
