ht motion with a 384000 km is the closest distance between earth and moon. Assuming the shuttle's acceleration is 20.7 m/s2 for the first time interval 14.6 min of the trip, then travels with a constant velocity until the last time interval 14.6 min , when it accelerates at − 20.7 m/s2 , just coming to rest as it reaches the moon. a- Find the maximum velocity reached? b- Which part of the total distance is traveled at constant velocity? c- How much time needed for the whole trip?
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.
Consider a space shuttle which carries life support material from
earth to moon. A straight motion with a 384000 km is the closest distance between earth and moon. Assuming the shuttle's acceleration is 20.7 m/s2 for the first time interval 14.6 min of the trip, then travels with a constant velocity until the last time interval 14.6 min , when it accelerates at − 20.7 m/s2 , just coming to rest as it reaches the moon.
a- Find the maximum velocity reached?
b- Which part of the total distance is traveled at constant velocity?
c- How much time needed for the whole trip?
