Calculating Final Speed After Acceleration

Question:

A car starting from rest accelerates uniformly at 3 m/s/s for 10 seconds. What is the car's final speed in m/s after the acceleration?

Final Answer:

The car's final speed after the acceleration is 30 m/s.

Explanation:

Using the formula v = u + at, where v is the final velocity, u is the initial velocity (which is 0 in this case), a is the acceleration, and t is the time, we can calculate the final speed.

Substituting the given values into the formula, we have v = 0 + (3 m/s2) * 10 s.

Simplifying, the final speed is 30 m/s.
