Answer:
The final speed of the masses is 8.75 m/s.
Explanation:
Given that,
Mass = 8.9 kg
Other mass = 2.9 kg
Distance = 7.7 m
Let mass start at its 0 Potential energy position.
Let mass start with potential energy from its position 4.6 m over final position.
We need to calculate the final speed of the masses
Using conservation of energy
Put the value in the equation
Hence, The final speed of the masses is 8.75 m/s.
Answer:
Meters
Explanation:"How FAR did the athlete run?"
Also it talked about meters
Answer:
26 m southwards.
Explanation:
From a North, East, South, West coordinate plane, moving northwards implies positive distance. While moving southwards implies negative distance.
Thus;
It moves 16 meters northward; d = 16 m
It now moves 22 meters southward; d = -22 m
It moves 12 meters northward; d = 12 m
It moves 32 meters southward; d = -32 m
Thus, total magnitude = 16 - 22 + 12 - 32 = -26 m
Thus, the object travels 26 m southwards.
