Answer: Velocity=8.26m/s
Explanation:
Acceleration=Finial velocity (V) - Initial velocity (u) ÷ Time
that is, a=v-u/t
a=1.2m/s², v=?, u=5.5m/s, t=2.3s
From a=v-u/t, make v the subject of the formula
v=at + u
v=(1.2* 2.3) + 5.5
v=2.76+5.5
v=8.26m/s
So we want to know what is the purpose of a lanyard attached to a safety switch. So in case the operator falls overboard a safety switch is installed and connected to the operators hand or waist. Which ever is more practical. This safety switch turns off the motor.
Ohms law = v= Ir
V= 0.02 x 4000 = 80v
Explanation:
Let magnitude of the two forces be x and y.
Resultant at right angle R1= √15N) and at
60 degrees be R2= √18N.
Now, R1 = √(x² + y²) = √15,
R2= √(x² + y² +2xycos50) = √18.
So x² + y² = 15,
and x² + y² + 1.29xy = 18,
therefore 1.29xy = 3,
y = 3/1.29x.
y = 2.33/x
Now, x2 + (2.33/x)2 = 15,
x² + 5.45/x² = 15
multiply through by x²
x⁴ + 5.45 = 15x²
x⁴ - 15x2 + 5.45 = 0
Now find the roots of the equation, and later y. The two values of x will correspond to the
magnitudes of the two vectors.
Good luck
