You could but you would get a quadratic because u is not 0 in this case. So you will end up with two values for t in the end which doesn't make sense. In this case one of my time values is a negative which also doesn't make any sense. So I prefer to avoid using that equation to solve for time.
well explained ma'am A projectile is a name given to a body which is given an initial velocity at an angle OTHER THAN 90 degrees and then allowed to fall under the influence of gravity. th-cam.com/video/0tq4fO16NLE/w-d-xo.html
Absolutely LOVED the video. Thanks a lot sir! Cheers!
my g
Man thank you!!
You saved me from failing in physics
in the first example, shouldn't g be positive? since the ball is moving downwards
Very helpful and nice handwriting!
Sir also make a video on impulse motion and conservation of momentum
This was amazing ty so much
love you man
Understood perfectly.
Please sir, make as many videos as you can.
Absolute plug
when you find height of y- component why you use initial velocity of y-component? why not use finial velocity of y- component
for the second question- second sub division; why can't we use ds= ut -1/2gt^2 formula
hello, in the question where we had to find the flight time of an arrow, wouldn't equation: s=ut+0.5at^2 work?

It is so helpful
thank you
thank you so much
What if time is not given but heiht is given
He said that at time 29 minutes in the video
Thank you
I can finally stop struggling
well explained ma'am
