Your friend's 10.8 g graduation tassel hangs on a string from his rearview mirror. When he accelerates from a stoplight, the tas
Nitella [24]

The tension in the string holding the tassel and the vertical will the tension in the string

  • T = 0.1953 N
  • Ф = 34.4 °

<h3>What is the tension in the string holding the tassel. ?</h3>

Generally, the equation for Tension is  mathematically given as

TCos\theta = mg

Therefore

TCos6.58^{o} = 19.8*10^{-3}*9.8

T = 0.1953 N

b).

Where

T* sin \theta = ma

0.1953*Sin6.58 \textdegree  = 19.8*10^{-3}*a

a = 1.13 m/s^2

In conclusion

T* sinФ = ma

2msinФ = ma

2sinФ = a

sin\theta = \frac{a}{2}

\theta = sin^{-1}\frac{a}{2} \\\\\theta= sin^{-1}\frac{1.13}{2}

Ф = 34.4 °

In conclusion, The tension in the string holding the tassel and the vertical will the tension in the string

T = 0.1953 N

Ф = 34.4 °

If the law of conversation of momentum is true,then how does the total momentum before a collision compare to the total momentum
Oxana [17]
<h2>Answer:The total momentum before collision is equal to the total momentum after collision.</h2>

Explanation:

Conservation of momentum states that whenever no external force is acting on a system,the total momentum is constant.

When we consider collisions,take the system as the two bodies that are colliding.

There are no external forces acting on the system.The forces that one body exerts on other come under internal forces.

So,momentum can be conserved in this case.

So,the total momentum before collision is equal to the total momentum after collision.
