2. A 25 kg block and 50 kg block are connected by a string as it shown below. The pulley has 10 cm radius and moment of inertia 1 kg.m?. The coefficient of friction between the 25 kg mass and the inclined is 0.250. If the inclination of the incline is 37°, determine: a. Acceleration of the blocks! b. Tension on each string! c. The angular speed of the pulley after 2 s! 25 kg 50 kg

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.
