Challenge Problems
Push your limits with challenges.
Question 1
If a projectile is launched at an angle of 60° with an initial speed of 50 m/s, calculate the horizontal range and maximum height reached. Assume g = 9.81 m/s².
💡 Hint: Use u_y = u * sin(θ) for vertical calculations, and the range formula for horizontal.
Question 2
A cannonball is fired horizontally from a height of 80 m with an initial speed of 24 m/s. How far will it land from the base of the cliff?
💡 Hint: First calculate the time of flight from height, then use horizontal velocity to find distance.
