Answer:
Vi = 4.38 m/s
Explanation:
Given
m = 1000 kg ;
y = 8m ;
T = 11000 N;
∑Fy = m*a
W - T = m * a
(1000kg * 9.8 m/s² ) - 11000N = 1000 kg * a
a = - 1.2 m/s²
Using the equation from parabolic motion
Vf ² = Vi² + 2*a*y
Solve to Vi
Vi = √ 2* 1.2m/s² * 8 m
Vi = √19.2 m²/s²
Vi = 4.38 m/s
Answer:
The last two bearings are
49.50° and 104.02°
Explanation:
Applying the Law of cosine (refer to the figure attached):
we have
x² = y² + z² - 2yz × cosX
here,
x, y and z represents the lengths of sides opposite to the angels X,Y and Z.
Thus we have,
or
substituting the values in the equation we get,
or
or
X = 26.47°
similarly,
or
or
Y = 49.50°
Consequently, the angel Z = 180° - 49.50 - 26.47 = 104.02°
The bearing of 2 last legs of race are angels Y and Z.
C) is correct
series circuit - in the same path : current flow on one path so they are equal on each component and equal to the source's. voltage on each components may be different.
parallel circuit - between same nodes : voltage of the components are equal and equal to the source's. current on each components may be different.
Answer:
The position, speed, direction and acceleration
I would say it would be magnetism if right can i have brainliest?
