Answer:
The heavier wagon rolls 1/2 as fast as the lighter wagon.
Explanation:
When the compressed spring that joins them is released then the force acts on both wagons will be of equal magnitude but in the opposite direction. However as the mass of one wagon is twice that of other, so the acceleration will become half of the heavier wagon in comparison with lighter one.
Answer:
they both would hit at the same time
Explanation:
Answer:
Diameter
Explanation:
I know that circumference is dependent, so diameter has to be independent
So it can be easily absorbed into the blood steam.
Answer:
The two stoned hit the water after 2.92s after the first stone satat to drop
Explanation:
We have this data:
x = distance = 47.2m
So = initial speed = 1.8m/s
A = In this case is equal to gravity = 9.8 m/s2
First we are going to calculate the final speed, We are going to use this equation
Where Sf= final speed
We put the data
We need to calculate the square root
The final speed is 30.47m/s
The next steep is calculate the time that the first stone spend during its drop.
We are going to use the next equation
We put tha data
We do not use 0.8s because we calculate all the things with the first stone, This stone spend more time that the second stone
