Answer:
T = 1.73 kg
Explanation:
Let's use Newton's second law for this balance problem
We draw a coordinate system with the x axis parallel to the plane and the Y axis perpendicular
The only force we have to lay down is the weight (W)
Wx = W sin θ
Wy = W cos θ
Wx = 2.0 ain 60
Wx = 1.73 kg
Wy = 2.0 cos 60
Wy = 1.0 kg
Y Axis
N-Wy = 0
X axis
T- Wx = 0
T = Wx
T = 1.73 kg
first of all the formula of force is F=ma,so we are searching for m,so we can divide a on both sides F/a=m, after this substitute the values given above 64N/4.51=14.2°Kg
In this item, we are asked for the word that would best fit in the blank of the sentence given above. The word that is missing in this item is "<em>evaporation</em>".
Evaporation is part of the water cycle wherein the liquid molecule of water is converted to water vapor and stays in the atmosphere until it is converted back to water for precipitation.
The vertical component of the stone's initial velocity is 0 because it was projected horizontally.
The horizontal component:
velocity = displacement / time
Vx = 60 / 3.19
Vx = 18.8 m/s
V = Vx
So the stone's initial velocity is 18.8 m/s
