1. a 100kg astronaut (including the space suit) becomes untethered during a space walk and drifts to a distance of 10m from the mother ship. To get back to the ship, he throws his 2.5kg tool kit away with an acceleration of 8.0ms-1 that acts over 0.50s. a) How does throwing the tool kit away help the astronaut in the situation? b) How large is the fact that acts on the tool kit and the astronaut? c) With that speed will the astronaut drift to the mother ship? d) How long will it take for the astronaut to reach the ship?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
