Homework Statement Simple Pendulum using Forces (Computer Simulation) Max theata = PI / 6 Force Of Gravity is { 0, 10 } Force_Tension.x = - 10 * sin(balls.theata); Force_Tension.y = - 10 * cos(balls.theata); Homework Equations accelleration = Force_Tension -...

You have as much information as I do. It is all stated above. It wants to know how much area the mirror must have. hence i find the Intensity possibly very useful, since I = P / A ... but how can P be related from the sun to the mirror

it's a spherical mirror...specifically a concave sphere... I know i have to use intensity but i don't know how i can relate the suns intensity to that of the mirror ; and / or power

correct...
