Problem 44P

An astronaut is tethered by a strong cable to a spacecraft. The astronaut and her spacesuit have a total mass of 105 kg, while the mass of the cable is negligible. The mass of the spacecraft is 9.05 × 104 kg. The spacecraft is far from any large astronomical bodies, so we can ignore the gravitational forces on it and the astronaut. We also assume that both the spacecraft and the astronaut are initially at rest in an inertial reference frame. The astronaut then pulls on the cable with a force of 80.0 N. (a) What force does the cable exert on the astronaut? (b) Since how can a “massless” (?m? = 0) cable exert a force? (e) What is the astronaut’s acceleration? (d) What force does the cable exert on the spacecraft? (e) What is the acceleration of the spacecraft?

Step-by-Step Solution:

Solution 44P Step 1: Mass of the astronaut (m) = 105 kg Mass of the cable = 0 Mass of the spacecraft (M) = 9.05 x 10 kg Spacecraft is free from astronomical bodies, there is no gravitational pull Problem (a) Step 1: Force applied by the astronaut = 80N Action = reaction Force exerted on the astronaut = 80N Problem (b) Step 1: Even though the mass of the cable is negligible, the rope can exert force on the...

Since the solution to 44P from 4 chapter was answered, more than 323 students have viewed the full step-by-step answer. The answer to “An astronaut is tethered by a strong cable to a spacecraft. The astronaut and her spacesuit have a total mass of 105 kg, while the mass of the cable is negligible. The mass of the spacecraft is 9.05 × 104 kg. The spacecraft is far from any large astronomical bodies, so we can ignore the gravitational forces on it and the astronaut. We also assume that both the spacecraft and the astronaut are initially at rest in an inertial reference frame. The astronaut then pulls on the cable with a force of 80.0 N. (a) What force does the cable exert on the astronaut? (b) Since how can a “massless” (?m? = 0) cable exert a force? (e) What is the astronaut’s acceleration? (d) What force does the cable exert on the spacecraft? (e) What is the acceleration of the spacecraft?” is broken down into a number of easy to follow steps, and 141 words.
