Calculating Horizontal Displacement of a Ball with Given Velocity and Time, Notas de estudo de Engenharia Elétrica

The formula for calculating the horizontal displacement of a ball given its constant horizontal velocity and the time it travels. An example calculation using a velocity of 160 km/h and converting the velocity to meters per second. The document also explains how to convert time units.

1. Assuming the horizontal velocity of the ball is constant, the horizontal displacement is
x=vt
where xis the horizontal distance traveled, tis the time, and vis the (horizontal) velocity. Converting
vto meters per second, we have 160km/h=44.4m/s. Thus
t=x
v=18.4m
44.4m/s=0.414 s .
The velocity-unit conversion implemented above can be figured “from basics” (1000 m = 1 km, 3600 s
= 1 h) or found in Appendix D.

  1. Assuming the horizontal velocity of the ball is constant, the horizontal displacement is

∆x = v∆t

where ∆x is the horizontal distance traveled, ∆t is the time, and v is the (horizontal) velocity. Converting v to meters per second, we have 160 km/h = 44.4 m/s. Thus

∆t =

∆x v =^
