A 60 kg astronaut pushes off a 100 kg satellite with 300 N for 0.50 s (g irrelevant in space). The acceleration of the astronaut during the push is
A.5.0 m/s²
B.3.0 m/s²
C.0.5 m/s²
D.300 m/s²
Explanation
Core Concept
The satellite pushes back with 300 N (third law), so a = 300/60 = 5.0 m/s².
Correct Answer
A5.0 m/s²
