There are several actions that can be used to increase the action force of a canoe that is moving through water. One can increase the rate of striking or strike harder than before with a bigger paddle. Using a lighter canoe can also be helpful for increasing the speed. I hope the answer comes to your help.
It's momentum is twice as much.
Answer: 24.7 km/h
Explanation:
1) Average speed definition and formula
The average speed is the total distance run divided by the time elapsed:
S = distance / time
2) Distance 1 = 67 km
3) Distance 2 = 81 km
4) Total distance traveled = 67 km + 81 km = 148 km
5) time 1 = 1 hour
6) time 2 = 5 hours
7) total time = time 1 + time 2 = 1 h + 5 h = 6 h
8) Average speed:
S = 148 km / 6 h = 24.7 km/h
Answer:
4.08 s
Explanation:
Let the passenger took "t" time to catch the train
so in this case the total distance moved by the train + 5 m = total distance moved by the passenger
so we will have
distance moved by train is given as
![d_1 = \frac{1}{2}(0.6) t^2](https://tex.z-dn.net/?f=d_1%20%3D%20%5Cfrac%7B1%7D%7B2%7D%280.6%29%20t%5E2)
also the distance moved by passenger
![d_2 = \frac{1}{2}(1.2) t^2](https://tex.z-dn.net/?f=d_2%20%3D%20%5Cfrac%7B1%7D%7B2%7D%281.2%29%20t%5E2)
so we will have
![d_1 + 5 = d_2](https://tex.z-dn.net/?f=d_1%20%2B%205%20%3D%20d_2)
![0.3 t^2 + 5 = 0.6 t^2](https://tex.z-dn.net/?f=0.3%20t%5E2%20%2B%205%20%3D%200.6%20t%5E2)
![0.3 t^2 = 5](https://tex.z-dn.net/?f=0.3%20t%5E2%20%3D%205)
t = 4.08 s
