50 POINTS + BRAINLIEST!!!


You want to calculate the displacement of an object thrown over a bridge. Using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Respuesta :

displacement = initial vel * time + 1/2 * accel * time^2

initial vel = 0 because the object was on the bridge be4 n had no vel.

accel = -10 and time = 8

so displacement = 0*8 + 1/2*(-10)*8^2

= -5*64

= -320m (-ve means down)
