Grade 11 Physics Mock Test: Kinematics
Instructions: Answer all questions. Show all calculations and include units in your answers.
Where applicable, draw diagrams.
Section A: Vectors and Resultant Calculations
1. Vector Addition (10 marks)
A person walks 4 km East and then 3 km North.
a) Draw a vector diagram representing the path.
b) Calculate the magnitude and direction of the resultant displacement.
2. Parallelogram Method (8 marks)
Two forces of 5 N and 8 N act at a point at an angle of 60° to each other.
a) Draw a diagram showing the forces.
b) Calculate the magnitude of the resultant force.
Section B: Kinematics and Motion Graphs
3. Equations of Motion (10 marks)
A car accelerates uniformly from rest to a speed of 25 m/s in 8 seconds.
a) Calculate the acceleration of the car.
b) Calculate the total distance traveled by the car in this time.
4. Graph Interpretation (7 marks)
A velocity-time graph shows an object moving with constant acceleration from 0 to
20 m/s in 5 seconds, and then moving at a constant velocity for another 5 seconds.
a) Sketch the velocity-time graph.
b) Calculate the total distance traveled in 10 seconds.
Section C: Projectile Motion
5. Horizontal Projectile (10 marks)
A ball is thrown horizontally from the top of a 45 m high cliff with a speed of 15 m/s.
a) Calculate the time it takes for the ball to hit the ground.
b) Calculate how far from the base of the cliff the ball lands.
6. Angled Projectile (15 marks)
A projectile is launched with an initial speed of 20 m/s at an angle of 30° above the
horizontal.
a) Calculate the horizontal and vertical components of the initial velocity.
b) Determine the time of flight.
c) Calculate the maximum height reached by the projectile.
d) Calculate the horizontal range of the projectile.
