Acceleration Practice: Finding Velocity After a Given Time

Calculating Velocity After 28 Seconds:

When an object accelerates from rest with a constant acceleration, we can use the equation:

v = u + at

Where:

v = final velocity

u = initial velocity (in this case, u = 0 as the object starts from rest)

a = acceleration

t = time

Given values:

Initial velocity (u) = 0 m/s

Acceleration (a) = 5.4 m/s^2

Time (t) = 28 seconds

Plugging in the values:

v = 0 + (5.4 m/s^2)(28 s)

v = 151.2 m/s

Therefore, the velocity of the object after 28 seconds would be 151.2 m/s.

It's important to maintain consistency in units throughout calculations for accurate results.
