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.
