It is a scalar value: m/s, cm/s, ect... with a direction attached to it: North, south, ect...
Hope this helps! :)
a) create an expression
for the ball's initial horizontal velocity, V0x, in terms of the variables
given in the problem statement.
v0x = vf * cos(Θf)
<span>
b) calculate the ball's initial vertical velocity, V0y, in
m/s</span>
v0x = 32.4m/s * cos(-25.5º)
= 29.2 m/s <span>
tanΘ = v1y / v0x → tan(-25.5) = v1y / 29.2m/s → v1y = -13.93
m/s
the vertical velocity when the ball was caught.
(v0y)² = (v1y)² + 2as = (-13.93m/s)² + 2 * 9.8m/s² * 5.5m = 301.78
m²/s²
v0y = 17.37 m/s
c) calculate the magnitude of the ball's initial velocity,
v0, in m/s</span>
v0 = sqrt (v0y^2 +
v0x^2)
v0 = sqrt (17.37^2 + 29.2^2)
m/s
v0 = 33.98 m/s
<span>
d) find the angle, theta0, in degrees above the horizontal at
which which the ball left the bat.</span>
tan Θ = v0y/v0x
<span>Θ = arctan(17.37/29.2) =
30.75º above horizontal</span>
Answer:
79.98
if this is a simple math problem, the (•) signifies multiplication

Absolutism is a form of government where all power is in the hands of a single ruler. In addition to being a tyrannical and dictatorial government, it exercises all 3 powers in one. The 3 powers are: executive, legislative and judiciary. In absolutism these powers are in the hands of the monarch, if he wants to create a law out of nothing, he goes there and does it. But this government doesn't work anymore (in fact it never did), it concentrates power in a single place and at one point it doesn't work anymore, because problems appear, like the one that led to the French Revolution. This government left the population with a great economic crisis, this caused revolts to happen and this government to fall.
Answer:
B. kinetic energy of particles decrease
Explanation:
when substance changes from gas to liquid the kinetic energy of it's molecules decreases.
