Answer:
It will travel 45 km (45000 m)
Explanation:
25 minutes is equal to 1500 seconds (25*60=1500)
distance=speed*time
distance=30m/s * 1500s = 45000 m = 45 km
Answer:
0.1014 J
Explanation:
Considering the air resistance negligible kinetic energy is given by
K.E = (1/2) m v^2
K.E = 0.5 x 0.12 x (1.3)^2
K.E = 0.06 x 1.69
K.E = 0.1014 J

I believe that the stack electricity forms a higher electricity rate
In order to catch up with the cockroach, the time it took for it to reach just before under the counter must be the same time for me to travel its covered distance. Thus,
time of cockroach = time of my motion
Time of cockroach = Distance/Constant Speed = 1.30 m/1.50 m/s = 0.867 seconds
We use this for the equation below:
x = v₀t + 0.5at²
0.75 m = (0.7 m/s)(0.867 s) + 0.5(a)(0.867 s)²
Solving for a,
a = 0.381 m/s²
