A race car starts from rest in the pit area and accelerates at a uniform rate to a speed of 37 m/s in 15 s , moving on a circular track of radius 500 m. The car's mass is 950 kg. a.)Assuming constant tangential acceleration, determine the tangential component of the net force exerted on the car (by the ground) when its speed is 15 m/s. Express your answer to two significant figures and include the appropriate units. b.)Determine the centripetal component of the net force exerted on the car (by the ground) when its speed is 15 m/s. Express your answer to two significant figures and include the appropriate units.
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.
