1 answer

Here are ten past questions from the West African Examinations Council (WAEC), National Examinations Council (NECO), and General Certificate of Education (GCE) exams focusing on the topic of projectiles. The questions span both objective and theory formats.

Objective Questions

  1. WAEC 2010 (Q. 15)
    A projectile is launched at an angle θ to the horizontal. Which of the following quantities remains constant throughout its motion?
    A. Vertical velocity
    B. Horizontal velocity
    C. Total energy
    D. Vertical acceleration

  2. NECO 2012 (Q. 19)
    The horizontal range of a projectile is affected by all of the following EXCEPT:
    A. The initial velocity
    B. The angle of projection
    C. The height of projection
    D. The acceleration due to gravity

  3. GCE 2013 (Q. 8)
    An object is thrown horizontally from the top of a tower. Which of the following is TRUE about its motion?
    A. It will take the same time to hit the ground as an object dropped vertically from the same height.
    B. The vertical and horizontal motions are independent.
    C. Its horizontal velocity remains constant.
    D. All of the above.

  4. WAEC 2015 (Q. 22)
    Which of the following factors does NOT affect the time of flight of a projectile?
    A. Initial velocity
    B. Angle of projection
    C. Height of projection
    D. Acceleration due to gravity

  5. NECO 2018 (Q. 10)
    A projectile projected at a certain angle will have its maximum height determined primarily by:
    A. The initial speed
    B. The angle of projection
    C. The horizontal distance
    D. The weight of the projectile

Theory Questions

  1. WAEC 2016 (Q. 9)
    (a) Define the term "projectile."
    (b) Derive the equation for the range of a projectile launched at an angle θ with an initial velocity v.

  2. NECO 2014 (Q. 12)
    A ball is thrown vertically upwards with a speed of 20 m/s. Calculate:
    (a) The time taken to reach its highest point.
    (b) The maximum height reached.

  3. GCE 2017 (Q. 7)
    Describe the path of a projectile in motion and explain the factors that affect its range. Include a sketch to illustrate your answer.

  4. WAEC 2018 (Q. 5)
    (a) State the conditions for a projectile to achieve maximum range.
    (b) A stone is thrown with a speed of 15 m/s at an angle of 30° to the horizontal. Calculate its range.

  5. NECO 2020 (Q. 15)
    An object is projected from the ground with an initial velocity of 25 m/s at an angle of 45°.
    (a) Calculate the time of flight.
    (b) Find the horizontal range of the projectile.

These questions will help prepare students for tackling projectile motion concepts in physics exams.
