Three strings, attached to the sides of a rectangular frame, are tied together by a knot as shown in the figure. The magnitude o
marta [7]

The magnitude of the tension in the string marked A and B is mathematically given as

A = 52.5 N

<h3>What is the magnitude of the tension in the string marked A?</h3>

Generally, the equation for is mathematically given as

tan=3/8

negative x

B= tan\phi \\tan \phi=5/4

negative x

C= tan=1/6

Hence, considering the Horizontal components

74.9cos(9.46) = A*cos(20.6) + B*cos(51.3)

A = 78.9 - 0.668B

Vertical components

74.9*sin(9.46) + Asin(20.6) = Bsin(51.3)

40.07 = 1.015B

B = 39.5 N

In conclusion, Sub the value of B is the equation of A

A = 78.9 - 0.668B

Sub

A = 78.9 - 0.668( 39.5 N)

A = 52.5 N

The kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s is
Arada [10]
The formula for kinetic energy is: KE = 1/2 x mass x velocity squared. We can plug in the information for the ball into this equation to determine the kinetic energy. The mass is 0.5 kg and the velocity is 10 meters per second. So: KE = (1/2)(0.5)(10)^2. Thus the kinetic energy of the ball is 25 J. The unit Joule (J) is the same as kgm^2/s^2 and is the SI unit for kinetic energy.
