Question

Space vehicle is moving vertically upward with constant acceleration a. An astronaut of weight mg feels heavier. When will Astronaut weight become 2mg

Answer 1

...................................

Answer 2

Answer :

Actual weight of astronaut = mg

We have to find upward acceleration of space vehicle so that apparent weight of astronaut become 2mg.

_________________________________

◈ When the space vehicle is accelerated up, then the apparent weight is more than the actual weight of the body$.$

Apparent weight of body when the space vehicle moves upward with acceleration a is given by

• Wapp = m(g + a)

➝ Wapp = m(g + a)

➝ 2mg = mg + ma

➝ ma = mg

➝ a = g

Hence, upward acceleration of space vehicle is g.
