EXERCISE 2.53 Collar C is pushed along the guide bar defined by y= 2(1-0.25x²), where x and y have units of meters. The angular speed of arm AB that actuates the motion is the constant value = 20 rad/s, so = ct. Determine the forces exerted on the collar by arm AB and the guide bar at x = 1 m. The mass of the collar is 2 kg, and gravitational effects are ignorable. (Hint: use Cartesian and polar coordinates to solve the problem.)

An object of mass m1 slides on a sloped block of mass M2, which in turn slides on a horizontal surface. The slope angle is a constant 3, and both masses are initially at rest. There is no friction between any of the objects, and the masses are subject to the force of gravity -mgêy. Use as co- ordinates the horizontal position x2 of mass m2, and the height y1 of mass m1, as shown in the y4 Y1 M2 x2 diagram to the right. Find the equation of motion of block 2, ä2(t). The expression should only include expressions involving constants: M2, m1, g, and B.
