A trapdoor mass m length l that is propped open at an angle, Ask an Expert

Academics

A trapdoor (mass M, length L), that is propped open at an angle θ, falls down, and stops only when it hits a pumpkin with its lower edge.

(a) What is the angular speed ω of the trapdoor when it hits the pumpkin?

(b) If it takes the time Δt for the pumpkin to fully stop the trapdoor, what is the average force F exerted on the pumpkin by the trapdoor?
