The spacecraft shown below weighs 6.1 million pounds. The rocket produces 7.5 million pounds of thrust. When the spacecraft falls back to earth, a parachute helps it fall safely. Explain the forces acting during this landing.

Question

the parachute's downward force resists gravity's upward force
the parachute's upward force resists gravity's downward force
the parachute's upward force resists gravity's upward force
the parachute's downward force resists gravity's downward force

Answer 1

During the landing of the spacecraft, the primary forces at play are the force of gravity and the force generated by the parachute. Here's the breakdown of the forces acting during this landing:

1. Gravity: The spacecraft has a weight of 6.1 million pounds, which means the gravitational force acting downward on it is also 6.1 million pounds.

2. Parachute: When the parachute is deployed, it generates a significant upward force (drag force) that counters the force of gravity acting on the spacecraft.

Considering the options provided:

• The correct explanation of the forces acting during the landing is: the parachute's upward force resists gravity's downward force.

This means that the parachute generates an upward force that counteracts the downward gravitational force, helping to slow the descent of the spacecraft and allowing for a safer landing.
