The distance d₁ it rises from rest while the engine is burning is given by
d₁ = d₀ + v₀t + (1/2)at²
d₁ = 0 + 0 + (1/2)·(29.4 m/s²)·(3.98 s)² = 232.85 m
So it gets to 232.85 m and then runs out of fuel. Its velocity v₁ at this point is given by
v₁ = v₀ + at = (29.4 m/s²)·(3.98 s) = 117 m/s
At this point, gravity begins to slow it down until it reaches its peak where its velocity v₂ is zero.
v₂² = v₁² + 2ad₂
where d₂ is the distance it rises until v=0
Since gravity is decelerating the rocket, a = -g, and we have
0² = (117 m/s)² + 2(-9.8 m/s²)d₂
0 = (117)² - (19.6)·d₂
0 = 13,689 - (19.6)·d₂
d₂ = 13,689/19.6 = 698.42 m
So the total height it rises is given by
d₁ + d₂ = 232.85 m + 698.42 m
= 931.27 m
Answer: The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if all of its components are zero. there is more than one force acting on an object, then F is the net force. If two people pull on an object with equal forces in opposite directions, then the net force is zero and the acceleration is zero
Explanation:
The tension of cold icebergs rubbing creates heat and it can also be how large the quantity is
Answer:
Blue light has the higher frequency.
Explanation:
Remember that the relation between wavelength and frequency for any electromagnetic wave in the vacuum is
where 
is the speed of light in the vacuum. As you can see, the relation between frequency and wavelength is inversely proportional. The higher is the wavelength, the lower is the frequency.
