The distance between astronaut and satellite after is

See the step by step solution

Step by Step Solution

Step 1 : Given information

An spacewalking astronaut pushes off a satellite, exerting a force for the it takes him to straighten his arms.

Step 2 : Calculation

The astronaut pushes the satellite with a force of and by Newton's , the force acting on the astronaut is also the same but in opposite direction.

The acceleration of the astronaut (a) can be evaluated by :-

Similarly, acceleration of the satellite can be evaluated by

Step 3 : Continuation of calculation

Relative acceleration

Distance between them after 60 s can be calculated as follows

Distance

Step 4 : Final answer

The distance between astronaut and satellite after is
