A small object with mass 4.30 kg moves counterclockwise with constant
speed 1.35 rad/s in a circle of radius 2.70 m centered at the origin. It starts at the
point with position vector 2.709 m. Then it undergoes an angular displacement of 9.50 rad. What direction is it moving in degrees? What is its acceleration in vector form? What is the total force exerted on the object?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
