From the equations of linear motion,
v² = u² + 2as where v is the final velocity, u is the initial velocity and a is the gravitational acceleration, and s is the displacement,
Thus, v² = u² -2gs, but v=0
hence, u² = 2gs
= 2×9.81×0.43
= 8.4366
u = √8.4366
=2.905 m/s
Hence the initial velocity is 2.905 m/s
Then using the equation v= u +gt .
Therefore, v = u -gt. (-g because the player is jumping against the gravity)
but, v = 0
Thus, u= gt
Hence, t = u/g
= 2.905/9.81
= 0.296 seconds
Cumulus and cumulonimbus<span />
Give u = start velocity
v = end velocity
v = u + at
50 = 400 + a*30
30a = -350
a = -116.67 m/
**Why the accecleration is negative number**
Because displacement, velocity, and acceleration are VECTOR QUANTITIES.
Vector Quantity must have direction.
The correct answer is letter b.
To find the answer follow the following steps.
1. 6524.96 x .25 = X
2. 1631.24 = X
This works for all of the given answers to find the correct answer.
b. is equally as toxic as carbon monoxide (CO).
Explanation:
Hydrogen Cyanide is a product of combustion that is equally as toxic as carbon monoxide CO.
The gas is a product of combustion in blast furnances, coke ovens, e.t.c
- Just like carbon monoxide, they are blood agents that are toxic in the body
- Prolonged exposure to hydrogen cyanide can lead to death eventually.
- The gas is a able to produce cyanide ion that seriously impacts the process of cellular respiration and bringing it to a halt.
- It is listed as one of the dangerous chemical weapons.
