Calculate the displacement for an object accelerating from rest at a rate of 7 m/s2 for 14 s.
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.
To calculate the displacement of an object accelerating from rest, we can use the equation:
displacement = (1/2) * acceleration * time^2
Given:
acceleration = 7 m/s^2
time = 14 s
Substituting the given values into the equation, we have:
displacement = (1/2) * 7 m/s^2 * (14 s)^2
Calculating further:
displacement = 0.5 * 7 m/s^2 * 196 s^2
displacement = 98 m
Therefore, the displacement for an object accelerating from rest at a rate of 7 m/s^2 for 14 s is 98 meters.
