I believe it is speed.
Hope this helps!
The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific
Answer:
v = 88.89 [m/s]
Explanation:
To solve this problem we must use the principle of conservation of momentum which tells us that the initial momentum of a body plus the momentum added to that body will be equal to the final momentum of the body.
We must make up the following equation:
where:
F = force applied = 4000 [N]
t = time = 0.001 [s]
m = mass = 0.045 [kg]
v = velocity [m/s]
![4000*0.001=0.045*v\\v=88.89[m/s]](https://tex.z-dn.net/?f=4000%2A0.001%3D0.045%2Av%5C%5Cv%3D88.89%5Bm%2Fs%5D)
Answer:
T1 cos 15 = T2 cos 26
T1 = T2 cos 26 / cos 15
T1 = 0.930 T2 ------------(1)
T1 sin 15 + T2 sin 26 = m g
substitute eqn(1)
(0.930 T2 ) sin 15 + T2 sin 26 = 230 * 9.8
0.241 T2 + 0.438 T2 = 2254
Tension in right cable T2 = 3319 N
substitute in eqn (1)
T1 = 0.930 * 3319
Tension in left cable T1 = 3087
