Throughout this problem, assume the air resistance is zero. A model rocket is launched straight upward from ground level (y = 0.00 m), at time t = 0.00 s. The rocket engine provides constant upward acceleration during the burn phase. At the instant of engine burnout, the rocket has risen to 88 m and acquired a speed upward of 60 m/s. At this point, the rocket continues to rise in unpowered flight (i.e. no engine burning) until it reaches its maximum height. After that, it free falls back to the ground. The speed of the rocket upon impact on the ground is closest to A) 60 m/s B) 89 m/s
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.

t=0.00s
The rocket has risen 88m away.
Speed=60m/s
Velocity=?
