wait wait no friction? why wouldnt there be friction? i did my graph incorporating friction as well

No because if the magnet wasnt there it shows a constant velocity remember the dotted line.

 

[SlimiJay]

I think so. Also the question would've been more amazing if there was friction from the floor aswell... But since V didnt change there was no friction...

think im going to get 0/5 for that easily the part i screwed up most

is there a paper uploaded?

I don't think so.

Was there a cheeky projectile?

Was there a cheeky projectile?

there was 1 projectile short answer which was extremely straight forward. There was also a projectile one as q20 of MC which nearly got me. I feel bad for those who do gen maths who may have struggled with that

yes it was so cheeky, i couldnt even do it.

you had to plot velocity and displacement on a graph, make ur own line of best fit, use that gradient to find time and then s=ut +1/2at^2 to do it. FML

 

[iforgotmyname]

Anyone got q21? The height of the wall? I found grqdient of line and subbed into y = ut +1/2 a_y t^2 where u = 0 and t = gradient. Lol dunno if its correct

Gradient is 1/t^2

how?

the time for the journey was like 0.7 seconds or something

 

[jacobnakz97]

Anyone have solutions yet?

 

[malcolm21]

guys for the force acting on the dc motor why was it worth 3 marks? do you just do bil? and bc is 0N?

 

[jacobnakz97]

Im sure Bc was 0 since theda was 0 degrees, and yea AB i think it was required you to use theda as 90 degrees

nice, was wondering why it looked so deceptively easy for a 3 marker..

Did you mention the direction of movement? I didn't see that it asked for the force on AB LOL

yeah i put it in cause i was scared they wanted it, it was downward i tihnk. I'm not sure if you even needed it though, lol which side did you do

No I did originally the one that required calculation and then I saw that it asked for another side so....

Hardest physics paper I have ever seen in all my years. Holy fuck.
