A cart of mass 5 kg attached to a spring rolls along a level table as shown. The wheels of the cart are good, so friction is negligible on the cart. The rest length of the spring is 0.2 m and its spring constant is 8.8 N/m. At the position shown, the length of the spring is 0.55 m and 0 =35.8 degrees. What is the magnitude of the acceleration of the cart at the position shown? (in m/s 2) 11. AO 0.365 BỘ 0.427 CO 0.500 DO 0.585 EO 0.684

Angular speed, acceleration and displacement

Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.

Angular Position

Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
