Concept explainers

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.

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 5.89 m/s. The stone subsequently falls to the ground, which is 13.1 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use g = 9.81 m/s2 for the acceleration due to gravity. impact speed: How much time is the stone in the air? elapsed time: m/s

A baseball player throws a baseball straight up into the air, in the following way: Starting from a height of 1.0 m above the ground, he accelerates the ball vertically with 30. m/s2 for 0.25 s, then the ball leaves his hand and flies straight up in free fall. Let’s ignore the air resistance. Draw a carefully labeled sketch of the situation. Calculate the velocity of the ball as it leaves the player’s hand. How high does the ball go relative to its initial position (yo=1.0 m)? Shows all work please.
A small rocket is launched straight up. When at a height of 5.0km and velocity of 200.0m/s, it releases its booster and enters free fall. Neglecting air friction, what is the velocity of the rocket at a height of 6.0km on its way up? 143m/s 200m/s 244m/s 397m/s

A Frisbee is lodged in a tree branch 7.0m above the ground. A rock thrown from below must be going at least 3.0m/s to dislodge the Frisbee. How fast must such a rock be thrown upward if it leaves the thrower's hand 1.3m above the ground? Express your answer using two significant figures.
At the lowest point of the waterfalls, water is moving at a speed of 40.0 meters per second. If the waterfall's height is 22.7 m. What is the water's velocity at the maximum height of the falls? A 36.89 m/s B 22.24 m/s 17.29 m/s D 14.93 m/s E) 33.99 m/s
A student launches a small rocket which starts from rest at ground level. At a height h=1.04km, the rocket reaches a speed of vf=391m/s. At that height, the rocket runs out of fuel, so there is no longer any thrust propelling it. After the rocket's engine turns off at a height of h=1.04km, it continues to move upward due to the velocity that it reached. What is the rocket's acceleration, in meters per squared second, during the period from engine shutoff until it returns to the ground? Ignore air resistance.
A ball is projected vertically up from the floor of a room. The ball experiences air resistance that is proportional to speed of the ball. Just before hitting the ceiling the speed of the ball is 10 m/s and its retardation is 2g. The ball rebounds from the ceiling without any loss of speed and falls on the floor 2s after making impact with the ceiling. How high is the ceiling? Take g = 10 m/s².
