Expert Answer

Step 1

Given,

Acceleration in y direction, a = 72.0 m/s2

Mass of the astronaut m=85.0kg

Step 2

When astronaut is on surface of earth then forces acting on astronaut are, Normal Force acting in upward direction and the weight of astronaut due to gravity.

Step 3

By Newton’s Second law of motion,
