Answer:
Step-by-step explanation:
OK... You have to use this formula: <u>Y2 - Y1</u>
X2 - X1
- -2 represents X1
- 7 represents Y1
- 2 represents X2
- -5 represents Y2
<u>Y2 - Y1</u>
X2 - X1
<u>-5 - 7</u>
2 - - 2
<u>-12</u>
-2
Simplify by dividing both -12 & -2 by 2: <u>-6</u>
-1
It's either <u>-6</u> or it's just -6 by itself... Really sorry if I'm wrong...
-1
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×
