Practice Questions

Test your understanding with targeted questions

Question 1 Easy

What is the resultant velocity if a boat travels at 15 m/s north and 20 m/s east?

💡 Hint: Use Pythagorean theorem: vR = √(v1² + v2²).

Question 2 Easy

Break down a 50 m/s velocity at 60° into its components.

💡 Hint: Use v_x = v cos(θ) and v_y = v sin(θ).

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

An athlete runs 100 m/s at 30° north of east. Resolve this into components and find the resultant velocity if it also runs at 20 m/s west.

💡 Hint: First resolve into components before adding vectors.

Challenge 2 Hard

A rocket is launched at 150 m/s at an angle of 45°. Calculate the time of flight if g = 9.81 m/s².

💡 Hint: Use vertical velocity to find time of flight.
