A bus starting from rest moves with a uniform acceleration of 0.1 ms-2 for 2 minutes. Find the speed acquired
Question
A bus starting from rest moves with a uniform acceleration of 0.1 ms⁻² for 2 minutes. Find the speed acquired.
Solution
Sure, here's how to solve this problem:
Step 1: Identify the given values. The problem gives us the following:
- Initial velocity (u) = 0 m/s (since the bus starts from rest)
- Acceleration (a) = 0.1 m/s²
- Time (t) = 2 minutes = 120 seconds (since 1 minute = 60 seconds)
Step 2: Use the formula for final velocity. The formula for final velocity (v) when you know initial velocity, acceleration, and time is: v = u + at
Step 3: Substitute the given values into the formula. v = 0 m/s + (0.1 m/s² * 120 s)
Step 4: Solve the equation. v = 0 + 12 m/s
So, the speed acquired by the bus is 12 m/s.
