If the person if slowing down, then this would mean that this would actually be "negative acceleration". Sense this person first did a mile in 10 minutes, and then the next mile that this person did was actually 15 minutes, then this shows you that they actually went a lot slower. And this is why this would be a great example of "negative acceleration".
The log of 4311 is 8.3689251747471
Answer:
heat and power
Explanation:
is the simultaneous production of electricity and heat both of which are used
Answer:
0.03 s
Explanation:
The maximum force is 90 N, and the mass is 0.2 kg, so we can find the deceleration:
F = ma
-90 N = (0.2 kg) a
a = -450 m/s²
The initial velocity is 14 m/s, and the final velocity is 0 m/s, so the time is:
v = at + v₀
0 m/s = (-450 m/s²) t + 14 m/s
t = 0.03 s
The fastest she can slow it down to a stop without breaking it is in 0.03 s.
Energy of the waves are redistributed to form a resultant wave with amplitude given by the summation of individual wave's amplitude.
