Question

Two acrobats flying through the air grab and hold onto each other in midair as part of a circus act.One acrobat has a mass of 60 kg and has a horizontal velocity of 5 m/s just before the grab.Another acrobat has a mass of 50 kg and has a horizontal velocity of -3 m/s just before the grab.Their horizontal velocity immediately after they grab onto each other is:

Answer 1

1.36m/s

Step-by-step explanation:

We are given that

Mass of one acrobat,
`m_1=60 kg`

Mass of another acrobat,
`m_2=50 kg`

`v_2=-3 m/s`

`v_1=5 m/s`

We have to find their velocity immediately after they grab onto each other.

The collision between two acrobat is inelastic

According to law of conservation of momentum

`m_1v_1+m_2v_2=(m_1+m_2)V`

Substitute the values

`60* 5+50(-3)=(60+50)V`

`300-150=110V`

`V=(300-150)/(110)=1.36m/s`
