Answer:
P = 5400[W]
Explanation:
We must use the following equation of kinematics to calculate the acceleration.
where:
Vf = final velocity = 9 [m/s]
Vo = initial velocity = 0 (starting from rest)
a = acceleration [m/s²]
t = time = 1.5 [s]
Now with this second equation of kinematics, we can determine the distance traveled.
where:
x= distance [m]
Now we must use Newton's second law which tells us that the sum of forces is equal to the product of mass by acceleration.
∑F = m*a
Now replacing:
Ahora la potencia se puede calcular por medio del producto de la fuerza por velocidad.
where:
P = power [W]
F = force = 600 [N]
v = velocity = 9 [m/s]
Matter is a lot like energy.
<em>It can't be created or destroyed</em>. It can only be moved around, shifted, rearranged, transformed, disguised, etc. Never created or destroyed.
If you suddenly see some matter that wasn't there a moment ago, it had to come from somewhere. It couldn't just appear out of nothing.
If you suddenly STOP seeing some matter that was there a moment ago, it had to go somewhere. It couldn't just disappear into nothing.
Answer:
1500 mph
Explanation:
Take east to be +x and north to be +y.
The x component of the velocity is:
vₓ = 889 cos 0° + 830 cos 59°
vₓ = 1316.5 mph
The y component of the velocity is:
vᵧ = 889 sin 0° + 830 sin 59°
vᵧ = 711.4 mph
The speed is found with Pythagorean theorem:
v² = vₓ² + vᵧ²
v² = (1316.5 mph)² + (711.4 mph)²
v = 1496 mph
Rounded to two significant figures, the jet's speed relative to the ground is 1500 mph.
Answer:
A
Explanation:
because you cannot seperate the matter duhhh hahha
