A rocket takes off from Earth’s surface, accelerating straight
up at 72.0 m/s2. Calculate the normal force acting on an astronaut
of mass 85.0 kg, including his space suit.


Expert Answer

Step 1


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,
