Answer:
1600 N
Explanation:
pascals principle says..
so lets do
so multiply one half (2/4 simplified) by 3200
1600 is equal to x
1600 N
YAAAAAAAAAAAAAAY
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae.
Answer:
The cue ball crashing into the eight balls on a pool table.
Explanation:
Elastic and inelastic collisions are two types of collisions.
For elastic collision, both the momentum and the kinetic energy before and after the collision remains conserved.
Out of the given options, the option that shows an example of an elastic collision is option A " The cue ball crashing into the eight balls on a pool table." All the eight balls after crashing moves with different velocity.
Answer:
a) v = 480 m / s
, b) t = 109.5 s
, c) v = 7.77 m / s
Explanation:
Let's use the kinematic equations
v² = v₀² + 2 a x
As part of rest v₀ = 0
v = 2 ax
Let's reduce the magnitudes to the SI system
x = 1.2 km (1000 m / 1 km) = 1200 m
v = 2 0.20 1200
v = 480 m / s
b) x = v₀ t + ½ a t²
x = 0 + 1/2 to t²
t = √ 2 x / a
t = √ (2 1200 / 0.2)
t = 109.5 s
c) the average speed is the distance traveled between the time interval
.x = 1200 m
Total time is travel time plus time that is stopped
t = 109.5 + 45
t = 154.5 s
v = x / t
v = 1200 / 154.5
v = 7.77 m / s
