Sir ypu are the best teacher in the world for numerical question solving

[@shinchan-kw5hr]

Sir you are the best for numerical
Thank you for your help 😊😊

[@shinchan-kw5hr]

Thanks for your like

[@Yajush-official-1980]

Great sir every one was one day before 😅 exam 😅

[@saloniiie26]

Time of ascent=Time of descent
Total time taken by the ball to return will be 5+5=10s

[@sriyamnaik4139]

Yes

[@raghavmittal9844]

Yes

[@pfsameer8169]

Thanks batane ke liye

Right

Very good sir my all doubt is cleared

[@James-gx4xx]

Me too

[@sriyamnaik4139]

But time is 10 sec not 5s

[@rajchaurasia323]

Second question is wrong
Because you have measured only upward time.
Question saying• ball take return to the surface of the earth 🌎

[@vaibhavmittal6442]

Yup

[@megladonegaming3674]

10 s hoga mera ko bhi laaga tha ki 10 s aayega kyuki jitna time jane mai lagega uthna time wapas aane mai bhi lagega

Sir in second part can we use 2nd equation of motion s is equal to ut+half at square ?

[@The_Raincoat]

yesss

Really sir you are great because mujhe bilkul bhi intrest nhi that physics me par jab aapse padha to bhut accha laga

V=u+gt
V=49 + 9.8 × t
9.8t = -49
T= 49/9.8
=5 sec. ( Yeti Jana ka h )
Ana ka 5 to 5+5 = 10 is total time

5s+5s=10s is the total time

[@jhonkhan2924]

Why did we take the value of acceleration due to gravity negative???

[@anshumanjain100]

Cause stone is oposing the gravity and its goind in the opposite direction of earth

[@ismail-t8n]

Sir
Second question is not fully answer the total time not 5 sec
Please reply sir
