1. Hi

These following questins are for a maths asignment that I have, could someone please check my answers so that I can make sure Im correct, as I found this question slightly difficult:

A) i)
Acceleration= gradient= change in y/change in x
5-2=3 =3x
5u-3u=2u

2u/3= 2/3u

ii)
3x3u= 9u
0.5(5yx3)=7.5u

9u+7.5u= 16.5u

B)
0.5(4x?)=20m
0.5(4x10u)=20m

u=10

Part B is where I was the most unconfident on

Thanks!
2. a i) 2u/3 is not the same as 2/3u just so you know. The former is correct.

ii) is wrong. it is a triange and a square. Square 3u x 3 = 9u. Triangle: 0.5 x 2u x 3 = 3u. Therefore 12u in total.

b) is wrong too.

A = 0.5bh
20 = 0.5(4)(5u) because you know that it is a straight line down from 5u.
5u = 10
u = 2
