Question

An object accelerates at 10 m/s², with an initial velocity of 5 m/s. What is the final velocity of the object, if the object took 5 seconds to accelerate?

Answer 1

To find the final velocity of the object, we can use the following kinematic equation:

v = u + at

Where: v = final velocity u = initial velocity a = acceleration t = time

Given: u = 5 m/s (initial velocity) a = 10 m/s² (acceleration) t = 5 s (time)

Substituting these values into the equation, we get:

v = 5 m/s + 10 m/s² × 5 s

v = 5 m/s + 50 m/s

v = 55 m/s

Therefore, the final velocity of the object after accelerating for 5 seconds is 55 m/s.
