Voltage of each component is same.
A. Translucent because it’s shows a little light on the inside and looks dark on the outside
Answer:
x- component = Fx= 4N
y - component= Fy= 3N
Explanation:
Fx=Fcos∅= 5cos 37= 3.99≅4N
Fy=F sin∅= 5 Sin37= 3.009≅3.01N
the dog pulls the pillow at an angle 37 degrees to the horizontal means it pulls it at an angle 37 degrees with the x- axis.if the line of the force represents the vector F then its horizonatal and vertical components wil be along x-axis and y-axis ie Fx and Fy.
as sin∅= Perpendicular/ Hypotenuse
but we have force F and Fy
so sin∅= Fy/F
or Fy= Fsin∅---------eqA
similarly cos∅= base /hpotenuse
cos∅= Fx/F
Fx= Fcos∅----------eq B
eq A and eq B can be used to determine the values of the rectangular components of the force making an angle with the horizontal
Answer:
1.28 m, 14 m/s
Explanation:
At the maximum height, the velocity is 0.
Given:
a = -9.8 m/s²
v₀ = 5.00 m/s
v = 0 m/s
x₀ = 0 m
Find:
x
v² = v₀² + 2a(x - x₀)
(0 m/s)² = (5.00 m/s)² + 2(-9.8 m/s²) (x - 0 m)
x = 1.28 m
The maximum speed is at the bottom of the well.
Given:
a = -9.8 m/s²
v₀ = 5.00 m/s
x₀ = 0 m
x = -8.5 m
Find:
v
v² = v₀² + 2a(x - x₀)
v² = (5.00 m/s)² + 2(-9.8 m/s²) (-8.5 m - 0 m)
v = -13.8 m/s
Rounded to 2 sig-figs, the maximum speed is 14 m/s.
