  1. 1A long-distance runner wishes to calculate her average speed for a race.
    Which calculation should she use?
    1. Aaverage speed = total distance / total time
    2. Baverage speed = total distance × total time
    3. Caverage speed = total time / total distance
    4. Daverage speed = total distance + total time
  2. 2A heavy metal ball falls vertically downwards through air past four equally spaced levels J, K, L and M.Imagen de la pregunta 2
    1. Aspeed is greatest between J and K: time is shortest between J and K
    2. Bspeed is greatest between J and K: time is shortest between L and M
    3. Cspeed is greatest between L and M; time is shortest between J and K
    4. Dspeed is greatest between L and M; time is shortest between L and M
  3. 3A ball is rolling down one hill and up another. Points A and B are at the same height on the two different hills . How do the velocity and acceleration change as the ball rolls from point A to point B?
    1. AThe velocity and acceleration are the same at both points.
    2. BThe velocity and the magnitude of the acceleration are the same at both points, but the direction of the acceleration is opposite at B to the direction it had at A.
    3. CThe horizontal component of the velocity is the same at points A and B, but the vertical component of the velocity has the same magnitude, but the opposite sign at B. The acceleration at points A and B are the same.
    4. DThe vertical component of the velocity is the same at points A and B, but the horizontal component of the velocity has the same magnitude, but the opposite sign at B. The acceleration at points A and B has the same magnitude, but opposite direction.
  4. 4The graph shows how the acceleration of an object moving in a straight line varies with time.
    Which graph shows the variation with time of the velocity of the object?    Imagen de la pregunta 4
    1. AAImagen de la opción A
    2. BBImagen de la opción B
    3. CCImagen de la opción C
    4. DDImagen de la opción D
  5. 5A ball is released from rest at time zero. After 1.0 s it bounces inelastically from a horizontal
    surface and rebounds, reaching the top of its first bounce after 1.5s.
    What is the total displacement of the ball from its original position after 1.5s?    Imagen de la pregunta 5
    1. AA 1.25 m
    2. BB 3.75 m
    3. CC 5.00 m
    4. DD 6.25 m
