Answer:
When you increase speed, you add energy and increase momentum as it would require more energy to change, stop or reverse the object's direction of travel than before the speed increase. Increasing the speed increases the momentum proportionally.
Explanation:
So the acceleration of gravity is 9.8 m/s so that’s how quickly it will accelerate downwards. You can use a kinematic equation to determine your answer. We know that initial velocity was 19 m/s, final velocity must be 0 m/s because it’s at the very top, and the acceleration is -9.8 m/s. You can then use this equation:
Vf^2=Vo^2+2ax
Plugging in values:
361=19.6x
X=18 m
The displacement of the object that moved 4 meters north, then 3 meters east is 5 meters.
<h3>
What is displacement?</h3>
Displacement is change in the position of an object. It can be described as the shortest distance between the initial and final position of an object.
The displacement of the object is calculated as follows;
d² = 4² + 3²
d² = 25
d = 5 m
Thus, the displacement of the object that moved 4 meters north, then 3 meters east is 5 meters.

Ye sit does. But since people weren’t there to hear it, doesn’t mean that it didn’t make a sound.
Answer:
a.
Explanation:
In a perfect system then energy can be changed from Kinetic to Gravitational Potential and vice versa without any losses. A common form of loss would be thermal energy, so b. is not the answer. c. is invalid as we want these 2 forms of energy to be transferred between, and d. is invalid as these statements c and a contradict each other.
