for question 6 if u have -2=9t - 5t^2 and u rearrange dont u get 5t^2 -9t - 2=0 not 5t^2 -9t +2=0 im confused did u take gravity to be 10 or -10?? i thought it would be 10 since the ball is falling and moving with gravity but the actual markscheme says its -10 could u pls explain why

[@harrison88352]

In question 7.(a)(i) wouldn't the value of the constant velocity of the train be in ms^-1 and not ms^-2, or am i mistaken?

[@PinkGem]

No you're right, it is ms^-1. I think he made a mistake

who takes 10 as gravity instead of 9.8..
