Since the initial velocity is 30 and the final is 0. 15 is the vave so you can use that with 1/2mv^2 to find the force
Weather balloons are filled with only a small amount of helium because the __Volume__. of the balloon will increase as the air pressure decreases at higher altitudes.
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
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

In physics, work is defined as the total energy when an object is moved to a certain displacement by the application of external force. It is calculated by the expression W = Fd. For this case, the displacement is apparently zero, then there is no work in the system above.
Since we are dividing a second in 2, we can simply divide the amount of meters by 2.
1500/2=750
It travels 750 meters in half a second.
Hope this helps!
