Answer:
averaage speed is v = 13 feet / s
Explanation:
The average speed is the ratio of the distance traveled in a given time interval, let's calculate the distance that the body travels in the two instants of time that give us
t = 1 s
d (1) = 2.6667 1²
d (1) = 2.6667 feet
t = 4 s
d (4) = 2.6667 4²
d (4) = 42.6672 feet
Let's calculate the speed
v = Δx / Δt
v = (42.6672 -2.6667) / (4-1)
v = 40/3
v = 13.33335 feet / s
v = 13 feet / s
First we will find the speed of the ball just before it will hit the floor
so in order to find the speed of the cart we will first use energy conservation
So by solving above equation we will have
now in order to find the momentum we can use
Answer:
- Grand Marais
- Two Harbors
- Duluth
Explanation:
The places that would would get snowfall because of the lake effect are Grand Marais, Two Harbors, and Duluth. The reason for this is that these three places are located right on the shores of the Lake Superior. This lake is one of the biggest lakes in the world. It has enormous amount of water in it, having big impact on the regional climate because of that. The water from this lake creates a lot of humidity in the air, and there's a lot of evaporation as well, both causing the formation of clouds, and when it is cold enough, instead of precipitation, the region gets large amounts of snowfall.
