spacecraft accelerates from rest: a = bt = 0.2t until a = 10.4, after which it continues at constant acceleration 10.4. Everything is in a straight line. a) How much time does it take to reach 10.4? (The base units are meters and seconds.) b) what are the dimensions of the number b in a = bt? c) a(t) = bt, with b=0.4, until a(t) = A = 9.3 , How fast is it going when the acceleration reaches A? d) how far does the spacecraft travel during its time of variable acceleration? b=1.0 and A = 8.9
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.
A spacecraft accelerates from rest: a = bt = 0.2t until a = 10.4, after which it continues at constant acceleration 10.4. Everything is in a straight line.
a) How much time does it take to reach 10.4? (The base units are meters and seconds.)
b) what are the dimensions of the number b in a = bt?
c) a(t) = bt, with b=0.4, until a(t) = A = 9.3 , How fast is it going when the acceleration reaches A?
d) how far does the spacecraft travel during its time of variable acceleration? b=1.0 and A = 8.9.
