Point C. at this point, which is the highest point, all of the ball’s energy is gravitational potential energy.
1) The acceleration
Acceleration = Change in Speed / Time
Acceleration = (12 - 2) / 2
Acceleration = 10 / 2
Acceleration = 5m/s^2 (This is the unit for acceleration)
2) Initial momentum
Momentum = Mass x Velocity
Momentum = 1500 x 2
Momentum = 3000kg m/s (This is the unit for momentum)
3) Final momentum
Momentum = Mass x Velocity
Momentum = 1500 x 12
Momentum = 18000kg m/s
4) Change in momentum
Change in momentum = Final momentum - Initial momentum
Change in momentum = 18000 - 3000
Change in momentum = 15000kg m/s
5) Force
Force = Mass x Acceleration
Force = 1500 x 5
Force = 7500N (This is the unit for force)
Hope that helps :)
The term sol is used by planetary astronomers to refer to the duration of a solar day on Mars.[7] A mean Martian solar day, or "sol", is 24 hours, 39 minutes, and 35.244 seconds.[6]
“Sol” is often used as a direct replacement for “Day” when concerning Mars. Mission duration for Mars missions is measured in Sols, so saying “Today is Sol xyz” would be normal, but I’m not sure if anyone would say “what a wonderful Sol tomorrow is going to be”.
<span>The rain shadow effect would be most evident in the “Eastern” direction in relative to the Rocky Mountains.
A “Rain-Shadow” is a dry area that is formed on the side of the mountains which are away from the wind. The rain-producing weather systems are blocked by the mountains and a shadow of dryness is cast on that area, without much moisture left in the air.
The Continental Divide in America acts as a great barrier for precipitation.
The Rocky Mountains are a major mountain range that is present in the western North America and stretch for more than 3,000 miles across the northern part of British Columbia, western side of Canada, till New Mexico, in the South-Western part of the US.
The low pressure systems are known to approach from the south to skirt the Rocky Mountains. They generate high precipitation on the eastern side. However, there is little or no precipitation on the western slope.

Answer:
1 N
Explanation:
1) You'll just have to sum the force vectors, and since they are opposite, you'll calculate the difference of their magnitudes, in absolute value.
Ftot = |F1 - F2| = 6N - 5N = 1N
2)The direction will be the same as the greater force's direction.
