2. In R3 you are given the points P(0,0, 10) and Q(42, 70, 4), and R(42, 70,-4) (a) Find the equation of the linear motion which travels through P at time 0 and through R at time 7 (b) Describe the motion of the particle which travels via linear motion, passing through P at time 0, then bounces off of the ry-plane and continues via a linear motion, until it passes though Q at time 14. (Draw a sketch of...
The centroid of a region R in the ry-plane having area A is the point with Cartesian coordinates (T, y) given by 3. -JIRZ dz dy, 9-Jl.ydzdy. The centroid would be the centre of mass if a plate in the shape of R was made out of a uniform density material.) Find the centroid (, ) of the circular sector given by the polar coordinate inequal- ities, where 0 < θ。< π/2. You are given the area A = R300....
