Answer:
Projectile motion is a form of motion where an object moves in a bilaterally symmetrical+ parabolic path.
Explanation:
<span>6.20 m/s^2
The rocket is being accelerated towards the earth by gravity which has a value of 9.8 m/s^2. Given the total mass of the rocket, the gravitational drag will be
9.8 m/s^2 * 5.00 x 10^5 kg = 4.9 x 10^6 kg m/s^2 = 4.9 x 10^6 N
Add in the atmospheric drag and you get
4.90 x 10^6 N + 4.50 x 10^6 N = 9.4 x 10^6 N
Now subtract that total drag from the thrust available.
1.250 x 10^7 - 9.4 x 10^6 = 12.50 x 10^6 - 9.4 x 10^6 = 3.10 x 10^6 N
So we have an effective thrust of 3.10 x 10^6 N working against a mass of 5.00 x 10^5 kg. We also have N which is (kg m)/s^2 and kg. The unit we wish to end up with is m/s^2 so that indicates we need to divide the thrust by the mass. So
3.10 x 10^6 (kg m)/s^2 / 5.00 x 10^5 kg = 0.62 x 10^1 m/s^2 = 6.2 m/s^2
Since we have only 3 significant figures in our data, the answer is 6.20 m/s^2</span>

of anaerobic exercise include sprinting and weight lifting.
Answer:
<em>Wave-Cut Platform</em>
Explanation:
A wave-cut platform, or shore platform <em>is the thin flat area frequently found at the bottom of a shore cliff or along a river, bay, or sea produced by erosion.</em>
When they become apparent as huge areas of flat rock, wave-cut platforms are often most noticeable at low tide.
