Hello and Welcome to Physics Practice Test – Projectiles

  1. You are to attempt 5 random objectives questions ONLY.
  2. Supply Your Full Name and Location in the text box below and begin immediately.
  3. You can attempt as many times as possible.
1. 



A ball X is projected from the platform RS with a horizontal velocity of 14 ms-1. If it takes 0.5s for the ball to fall freely from R to P, (see the diagram), the distance PQ is _____

A. 28.0 m  B. 14.5 m   C. 9.5 m   D. 7.0 m

2. 


Why the horizontal component of the velocity of a projectile remains the same at every point of its flight? (WASSCE 2015)

A. Because the time taken on both components is the same
B. Because the velocity varies along the path of the projected object
C. Because the vertical component of the velocity is the higher.
D. because the acceleration due to free fall (g) does not act in the horizontal direction.

3.

I. Vertical acceleration on the ball decreases as it falls
II. The vertical force on the ball remains constant
III. The vertical speed of the ball increases as it falls

A. I only    B. II only.     C. I and II only     D. II and III only

5. 


A stone is thrown horizontally with initial velocity 15 ms-1 from a tower 20 m high. How long does it take to reach the ground? [g = 10 ms-2] (WASSCE 2021)
