What is the mass of a 70-kg astronaut floating in space

0.062  m/s

Explanation:

Quantities:

m a = 70  kg

m o = 26  kg

v o f = 1 6  m/s

v a f = ?  m/s

v a i = v o i ≡ v i  m/s

p a i + p o i =p a f + p o f

m a v a i + mo v o i = m a v a f + m o v o f

( m a + m o) v i = m a v a f + m o v o f

( 70 + 26 ) v i = ( 70 ) v a f+ ( 26 ) ( 1/6)

96 v i = 70 v a f+  13/3

We can assume that the initial speed of the astronaut is zero for the sake of argument. It says "floating in space", so maybe that actually means 0. The actual initial and final speeds are unimportant, because we are just looking for the change (or difference) in the two speeds.

− 13 /3 = 70 v a f

v a f = − 0.062  m/s

This means that the astronauts speed will change by  0.062   m/s and the astronaut will move in the opposite direction of the object (hence the minus sign).

Surface waves, in contrast to body waves can only move along the surface. They arrive after the main P and S waves and are confined to the outer layers of the Earth. They cause the most surface destruction. Earthquake surface waves are divided into two different categories: Love and Rayleigh.
