When jumping, a flea reaches a takeoff speed of 1.0 m/s over a distance of 0.50 mm.a. What is the flea’s acceleration during the jump phase?b. How long does the acceleration phase last?c. If the flea jumps straight up, how high will it go? (Ignore air resistance for this problem; in reality, air resistance plays a large role, and the flea will not reach this height.)
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.

The (c) answer is incorrect, the height the flea gets should be 0.051 m, not 4.95 x 10 ^ -6. Because its initial velocity after accelerating is 1 m / s, and the flea travels approximately 0.051 m before its velocity decreases to 0. Adding 0.051 m to 0.0005 m should get 0.051 m after rounding. Please check and edit the answer again.
