Physicist I am unable to help her. I am not much of any help. Help her.Yea i know But WHYYY
We've got everything except displacement why can't we use this eq

The eq u used isn't it incomplete ? where is u*t? initial velocity is not even O in this case?[/QUOTE]Find the time with, t = s/v = 5.5/32 = 0.171875
Then use s = 1/2at^2 = 5*0.171875^2 = 0.15m
The DISPLACEMENT is negative and is subtracted before calculating average velocity.
See in such questions related to projectile motion, we need to deal with the horizantal and vertical components separately.Yea i know But WHYYY

There's no P3 solved on this site :/explanation are available at

hope it helps
just calculate the change p-(-p)=2pdid not have the answer to this one....
A ball having a momentum p hits a bat and its momentum becomes -P. what is the change in momentum of the ball?
Change in momentum = Final momentum - Initial momentumjust calculate the change p-(-p)=2p
can someone please provide me with As level PRACTICAL tips and tricks. Any help will be highly appreciated
A is a guess.On a particular railway, a train driver applies the brake of the train at a yellow signal, a distance of
1.0km from a red signal, where it stops.
The maximum deceleration of the train is 0.2ms–2
.
Assuming uniform deceleration, what is the maximum safe speed of the train at the yellow signal?
A 20ms–1 B 40ms–1 C 200ms–1 D 400ms–1
I am in hurry, so make two parts diagram, on from yellow to red n till brakes.. Which is asked in the question.yes A is the answer but how ?
yea u are right broChange in momentum = Final momentum - Initial momentum
Hence in shouldn't be -P - P = -2P?
Thanx a lot MAY GOD BLESS YOU
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
