The 20 questions

  1. Which constant-acceleration formula relates v, u, a and t?

    • v^2 = u^2 + 2as
    • s = ut + (1/2)at^2
    • v = u + at
    • s = vt + at^2
  2. Which constant-acceleration formula does not involve time t?

    • v^2 = u^2 + 2as
    • s = (u + v)t / 2
    • v = u + at
    • s = ut + (1/2)at^2
  3. A body has u = 4 m s^-1, a = 3 m s^-2 and t = 5 s. What is v?

    • 12 m s^-1
    • 7 m s^-1
    • 15 m s^-1
    • 19 m s^-1
  4. A body starts from rest with a = 2 m s^-2. How far does it travel in 6 s?

    • 12 m
    • 72 m
    • 36 m
    • 18 m
  5. A body's velocity changes uniformly from 10 m s^-1 to 30 m s^-1 in 4 s. What is its displacement?

    • 20 m
    • 160 m
    • 80 m
    • 40 m
  6. A car moving at 20 m s^-1 decelerates uniformly at 5 m s^-2 until it stops. How far does it travel?

    • 80 m
    • 40 m
    • 100 m
    • 20 m
  7. Which step is used to derive v = u + at from the definition of acceleration?

    • Rearranging a = (v - u)/t
    • Differentiating velocity with respect to displacement
    • Using s = vt for the whole journey
    • Integrating displacement with respect to time
  8. Why does s = (u + v)t/2 hold for constant acceleration?

    • Acceleration equals the average velocity
    • The velocity-time graph is a rectangle
    • The average velocity is (u + v)/2 when acceleration is constant
    • Displacement equals the product of u and v

  10. A particle has initial velocity u = 3i + 4j m s^-1 and constant acceleration a = 2i m s^-2. What is its velocity after 2 s?

    • 3i + 8j m s^-1
    • 7i + 8j m s^-1

    • 2:3
    • 4:1
    • 2:1
    • 3:1

    • 75 m
    • 160 m
    • 200 m
    • 235 m
