Answer:
This could represent something like sliding a small rock across an icy lake.
Explanation:
A 20N force of gravity (weight), and 20N normal force exerted back onto the object imply it is on the ground and has no vertical motion. There is a net force of 0N
An 80N force to the left and a 5N force to the right create a net force of 75N to the left. This means that there is a force acting on the object that makes it accelerate to the left. 80N represents a push or pull force and 5N represents a relatively small frictional force due to the object being slid on a surface such as steel or in this case ice.
ELECTRICITY IS A FUNDAMENTAL FORM OF ENERGY OBSERVABLE IN A POSITIVE AND NEGATIVE FORM WITHIN A CONDUCTOR WHILE LIGHT ENERGY IS MOSTLY THE FORM OF ENERGY THAT SHOWS WHEN ELECTRICITY IS GENERATED
Depends on how strong you are. People can hit it anywhere between a few inches and 500 yards.
Answer:
The height of the building is 88.63 m.
Explanation:
Given;
initial component of vertical velocity, = 12 m/s sin 26° = 5.26 m/s
initial horizontal component of the velocity, = 12 m/s cos 26° =10.786 m/s
horizontal distance traveled by the rock, x = 40.4 m
time of flight is calculated as;
x = t
t = x /
t = 40.4 / 10.786
t = 3.75 s
Determine the final vertical velocity of the ball;
Determine the height of the rock;
Therefore, the height of the building is 88.63 m.
Answer:
the answer is 375°F
Explanation:
you simply subtract 250°F from 625°F
