During a period of accelerating from zero to 24 m/s, the average speed is 12 m/s.
It is impossible for a dt-graph to have a vertical line. This would mean that you are at many places at one point in time. It simply can't be done, because we can't teleport lol. You can, however, have a line that is REALLY steep. This would mean that you're travelling really fast. (Covering large amounts of distances in short spans of time) Hope this helped!
Answer:
7.5 N/m
Explanation:
Potential energy of a spring can be calculated using below formula
Potential energy= 1/2kx^2
potential energy = 60 J
X= displacement = 4 m
K= spring constant=?
Substitute the values we have
60= 1/2 × K × 4^2
60= 1/2 × K × 16
60= K × 8
K= 7.5 N/m
Hence, the spring constant of the spring is 7.5 N/m
B is the correct answer I believe
Answer:
Muscular helps you move while Cardiovascular helps you breathe, not move. Hope this helps, I tried my best :)
Explanation:
Muscular endurance relates to how your body is able to move, your muscles.
Cardiovascular is how your body supplies blood and helps you breathe, (an organ in this system is heart) :)
