Answer: 71 degrees
Explanation:
Complimentary means that a pair of angles add up to 90 degrees.
Let's call the first angle A and the second angle B.
Then,
A + B = 90 and
A = 4B - 5 (5 less than 4 times the angle)
Now we can solve for A and B:
A + B = 90
-(A = 4B - 5)
So
A + B = 90
-A = -4B + 5
B = -4B + 95
B + 4B = 95
5B = 95
B = 19
Now we can plug in B to solve for A.
A + B = 90
A + (19) = 90
A = 90 - 19
A = 71
The question asks for the number of degrees in the larger of the two angles, which is 71 degrees.
Answer:
The kinetic energy of the bob on a simple pendulum swinging in simple harmonic motion has its maximum value when the displacement from equilibrium is zero.
According to the principle of conservation of mechanical energy, the total kinetic energy any point is equal to the total potential energy.
M.A = K.E + P.E
As the kinetic energy of the bob decreases, the potential energy increases and becomes maximum when the velocity is zero.
Also, as the potential energy of the bob decreases, the kinetic energy increases, and becomes maximum when the displacement is zero
Thus, we can conclude that, the kinetic energy of the bob on a simple pendulum swinging in simple harmonic motion has its maximum value when the displacement from equilibrium is zero.
The change in the kinetic energy of the system from when it is released to the instant it hits the ground is most nearly; (My + Mx)gH
We are told that the two objects X and Y are held together by a light string.
Their masses are;
Mass of Object X = Mx
Mass of objetc Y = My
Since the two objects are released from rest, it means we need to find potential energy and the formula for potential energy is;
P.E = mgh
Now, since both objects are released from rest and since My is larger than Mx, it means that potential energy is now;
ΔP.E = (My + Mx)gH
Now, according to conservation of energy,
Change in kinetic energy = Change in potential energy.
Thus;
Change in kinetic energy = (My + Mx)gH
