A ball is thrown upward from the ground with velocity vi= 14 m/s and reaches height of h above the ground before falling back down. Take the upward direction to be positive. Refer to the figure. Neglect Air resistance. The acceleration in m/s to the ball when it is in the air is -9.8 m/s. The velocity of the ball in meters sped second, when it reaches the top of its trajectory is 0 m/s. Enter an expression for the maximum height, h, the ball reached in terms of vf, vi, and a. The value of h in meters is 10 m. Enter an expression for the time it takes for the ball to travel from the ground to the top, delta t, in terms of vi, vf, and a. The value of delta t in seconds is 10s. The total displacement in meters, of the ball going through its entire motion: reveling from the ground to the tio and then falling back to the ground is 0m. Enter an expression for the total time of flight of the ball: the time from when it is launched to when it lands back in the ground. Express this in terms of vi and a. The value of delta t subscript tot in seconds is 2.86s. Enter an expression for delta t, subscript tot in terms of the variable delta t, the time of ascent from the friend to the top of the trajectory. Express the velocity of the ball right it hits the ground, vf, in terms of vi, delta t1 and a. Express vf in terms of vi.
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.
