Answer:
0.9378
Explanation:
Weight (W) of the rider = 100 kg;
since 1 kg = 9.8067 N
100 kg will be = 980.67 N
W = 980.67 N
At the slope of 12%, the angle θ is calculated as:

The drag force D = Wsinθ

where;

A = 0.9 m²
V = 15 m/s
∴
Drag coefficient 


On Earth, about 29 grams of mass weigh one ounce
Answer:
Each jump covers one center of the square to the other. If you can imagine the scenario, a single jump would cover a length of the side of one whole square. So, if it took three jumps, the total distance would be
d = 3 * 5 cm
d = 15 cm
Therefore, the magnitude or distance is 15 cm. The displacement depends on the direction of motion.
Answer:
An example of positive velocity is throwing a ball upwards
An example of downward vertical velocity is when an object is dropped, for example a ball dropped from a height
Explanation:
In a vertical movement the acceleration is always downwards, therefore negative since it is created by the attraction of the Earth on the body.
An example of positive velocity is throwing a ball upwards
An example of downward vertical velocity is when an object is dropped, for example a ball dropped from a height
Applying force all the time is bad for you body, the object, and the environment and how it looks at you. First of all, you could strain, break, fracture, you name it, to your bones and muscles. Second of all, you could manage to break that object, not even move it. For example, say you have to move a heavy object to save the town from almost flooding and you strain or break your arm. To society or the people watching you do this, you look like a wimp or you're not strong. Then you have a bad reputation in the people's eyes and you get picked on or bullied because of that. You don't have move that object. You could find a way to work around the object and get simpler ways that only you thought of at the time.
