Questions & Step-by-Step Solutions
If a vehicle accelerates from 0 to 60 m/s in 12 seconds, what is its acceleration?
Step 1: Identify the initial speed (u) of the vehicle. In this case, u = 0 m/s.
Step 2: Identify the final speed (v) of the vehicle. Here, v = 60 m/s.
Step 3: Identify the time (t) it takes to accelerate. In this case, t = 12 seconds.
Step 4: Use the formula for acceleration: a = (v - u) / t.
Step 5: Substitute the values into the formula: a = (60 - 0) / 12.
Step 6: Calculate the difference: 60 - 0 = 60.
Step 7: Divide the result by the time: 60 / 12 = 5.
Step 8: Conclude that the acceleration is 5 m/s².
Acceleration – Acceleration is the rate of change of velocity over time, calculated using the formula a = (v - u) / t, where v is final velocity, u is initial velocity, and t is time.
