ScanSolve AI Answer

Answer

The car's acceleration is 5 m/s².

Step-by-step solution

3 steps

Steps:

  1. Identify the given values

    • Initial velocity (u) = 0 m/s
    • Final velocity (v) = 20 m/s
    • Time (t) = 4 s

  2. Use the formula for acceleration

    • a = (v - u) / t

  3. Substitute the values into the formula

    • a = (20 m/s - 0 m/s) / 4 s
    • a = 20 m/s / 4 s
    • a = 5 m/s²
