Scot would have 4 football cards..
Not 100% sure
Sorry =,(
You only need to know one side, you can use , tan, sin, or cos of the angles to find the other 2 sides.
Actually the answer is
-3x + 5y = 15
2x + 3y = -10
Answer:
As the first part comes to the rest means, then it will fall under gravity directly.
First of all maximum height,
H=
g
u²sin²θ
H=
2×10
400×(
2
1
)
H=10m.
As initially the full projectile was supposed to land at A but due to explosion first part land at A', so to make the centre of mass lies at A the second part should lie at B.
f they don't break (explode) range OA
OA=
g
u²sin2θ
OA=400×sin45×
