Weight component down a ramp
A \(13\,\text{kg}\) trolley in a collision track investigation is on a ramp inclined at \(50^{\circ}\). Use \(g=9.8\,\text{m s}^{-2}\). Calculate the component of weight down the ramp. Use the diagram before entering the requested value. Enter the numerical result and choose the interpretation that matches the physics meaning.
Worked practice: physics data and result
Read the physical quantities first, then calculate the result and state what it means.
