Answer:
7.150 KJ
Explanation:
The total energy of a system is the sum of the potential and kinetic energy in the system. According to this question, the kinetic energy (KE) = 1368 J and a potential energy (PE) = 5782J.
Total energy of the system will be PE + KE as follows;
1368J + 5782J
= 7150J
However, the question demanded that the answer be in kJ (kilojoules), which is higher than the joules.
Since 1kJ = 1000J
7150J = 7150/1000
= 7.150kJ
Frequency. This refers to how often you exercise. The point is to meet your goals without overtraining the body. When it comes to cardio: As a general rule of thumb, aim for a minimum of three cardio sessions per week.
I believe anticline (caused by compressional stress)
<span>x = 129.9 m
y = 30.9 m
First, let's calculate the horizontal and vertical velocities involved
h = 50.0cos(30) = 43.30127 m/s
v = 50.0sin(30) = 25 m/s
The horizontal distance is simply the horizontal velocity multiplied by the time, so
43.30127 m/s * 3 s = 129.9 m
So the horizontal distance traveled is 129.9 m, so x = 129.9 m
The vertical distance needs to take into account gravity which provides an acceleration of -9.8 m/s^2, so we get
d = 25 m/s * 3s - 0.5*9.8 m/s^2 * (3 s)^2
d = 75 m - 4.9 m/s^2 * 9 s^2
d = 75 m - 44.1 m
d = 30.9 m
So the vertical distance traveled is 30.9 m, so y = 30.9 m</span>
