Question

Calculate the displacement for an object accelerating from rest at a rate of 7 m/s2 for 14 s.

Answer 1

To calculate the displacement of an object, we can use the equation:

displacement = initial velocity * time + 0.5 * acceleration * time^2

Given the following values:

initial velocity (u) = 0 m/s

acceleration (a) = 7 m/s^2

time (t) = 14 s

Plugging these values into the equation, we have:

displacement = 0 * 14 + 0.5 * 7 * (14^2)

displacement = 0 + 0.5 * 7 * 196

displacement = 0 + 0.5 * 1372

displacement = 0 + 686

displacement = 686 m

Therefore, the displacement for an object accelerating from rest at a rate of 7 m/s^2 for 14 s is 686 meters.
