Assume that a clay model of a lion has a mass of 0.225 kg and travels on the ice at a speed of 0.85 m/s. It hits another clay mo

del, which is initially motionless and has a mass of 0.37 kg. Both being soft clay, they naturally stick together.
What is their final velocity?

Answer:

Final velocity will be equal to 0.321 m/sec

Explanation:

We have given mass of clay model of lion m_1=0.225kg

Its speed is 0.85 m/sec, so v_1=0.85m/sec

Mass of another clay model m_2=0.37kg

It is given that second clay is motionless

So its velocity v_2=0m/sec

Now according to conservation of momentum

Momentum before collision will be equal to momentum after collision

So m_1v_!+m_2v_2=(m_1+m_2)v, here v is velocity after collision

So 0.225\times 0.85+0.37\times 0+(0.225+0.37)v

0.595v=0.191

v = 0.321 m/sec

So final velocity will be equal to 0.321 m/sec

A circus tightrope walker weighing 800 N is standing in the middle of a 15 meter long cable stretched between two posts. The cab
Lorico [155]

Answer:

T = 10010 N

Explanation:

To solve this problem we must use the translational equilibrium relation, let's set a reference frame

X axis

       Fₓ-Fₓ = 0

       Fₓ = Fₓ

whereby the horizontal components of the tension in the cable cancel

Y Axis  

        F_{y} + F_{y} - W =0

        2F_{y} = W

let's use trigonometry to find the angles

        tan θ = y / x

        θ = tan⁻¹ (0.30 / 0.50 L)

        θ = tan⁻¹ (0.30 / 0.50 15)

        θ = 2.29º

the components of stress are

         F_{y} = T sin θ

we substitute

       2 T sin θ = W

       T = W / 2sin θ

        T = \frac{ 800}{ 2sin 2.29}

        T = 10010 N
