Challenge Problems
Push your limits with challenges.
Question 1
A drone weighs 1.5 kg and has a wing span of 1.2 m. Calculate the lift force required for the drone to take off considering a lift coefficient of 1.2 at a velocity of 8 m/s.
💡 Hint: Use the lift equation for your calculations.
Question 2
An object has a drag coefficient of 0.1 and a cross-sectional area of 0.5 m². Calculate the drag force it experiences at a velocity of 15 m/s in air (density = 1.225 kg/m³).
💡 Hint: Make sure to plug values accurately into the drag equation.
