Two masses are on a horizontal, frictionless surface. The plane of the surface is the x-y plane. Mass m1 = 1.0kg is at rest while mass m2 = 2.0kg is moving in the positive x-direction at 15m/s. The two masses then undergo a collision and mass m2 is moving with a speed of 9.0m/s at an angle of 35 degrees after the collision. 1) What is the speed of the center of mass of the two masses before the collision?...

Find the equation of the plane tangent to the function f(x, y) = (x^2)(y^2) cos(xy) at x = y = π / √ 2 . Using this linearization to approximate f, how good is the approximation L(x, y) ≈ f(x, y) at x = y = π / √ 2 ? At x = y = 0? At (x, y) = (π, π)?
