Change in Momentum = mv - mu.
u = 0, v = 10 m/s. Note ball accelerated from rest, so initial velocity = 0. u =0
Change in Momentum = mv - mu = 3*10 - 3*0 =30.
Change in Momentum = 30 kgm/s.
Answer: Hipparchus & Ptolemy believed sun and moon travel around circles with Earth in the middle (geocentric) while Plato and Aristotle believed Perfect unchanging heavens
Explanation: thus hipparchus and ptolemy violate early greek philosophy
Answer:
At the bottom when they hit the ground.
Answer:
the direction of rate of change of the momentum is against the motion of the body, that is, downward.
The applied force is also against the direction of motion of the body, downward.
Explanation:
The change in the momentum of a body, if the mass of the body is constant, is given by the following formula:
p: momentum
m: mass
: change in the velocity
The sign of the change in the velocity determines the direction of rate of change. Then you have:
v2: final velocity = 35m/s
v1: initial velocity = 40m/s
Hence, the direction of rate of change of the momentum is against the motion of the body, that is, downward.
The applied force is also against the direction of motion of the body, downward.
High-density altitude and high humidity do not ever go hand in hand. If high humidity does exist, however, it exists wise to add 10 percent to your calculated takeoff distance and expect a reduced climb rate.
With a longer takeoff distance, the air exists less dense.
<h3>How do atmospheric temp pressure and rel humidity affects aircraft performance?</h3>
Several elements (altitude/pressure, temperature, and humidity) affect air density. A more elevated altitude, low-pressure area, higher temperature, and increased humidity all contain one effect: they lower the density of the air. And as a consequence of that: a decrease in aircraft and engine performance.
Humidity reduces the implementation of most aircraft, not only because of its effect on the wings but also effect on the engines. Humidity contains a significant effect on the path of plane flies. This exists due to the weight of the air when it exists in humid.
