Question

A car accelerates uniformly from rest and attains a velocity of \( 20 \, \text{m/s} \) in 10 seconds. What is the acceleration of the car?

• A. \( 2 \, \text{m/s}^2 \)
• B. \( 1 \, \text{m/s}^2 \)
• C. \( 4 \, \text{m/s}^2 \)
• D. \( 5 \, \text{m/s}^2 \)

Hint:

When solving problems on uniform acceleration, use the equations of motion, such as \( v = u + at \), to find the unknown quantities.
