A racing car travels with a constant tangential speed of 75.0 m / s around a circular track of r

step 1 Hi everyone here it is given. A racing car is moving with tangential velocity of 75 meter per se

A racing car travels with a constant tangential speed of...

A racing car travels with a constant tangential speed of $75.0 \mathrm{m} / \mathrm{s}$ around a circular track of radius $625 \mathrm{m}$. Find (a) the magnitude of the car's total acceleration and (b) the direction of its total acceleration relative to the radial direction.

Key Concepts

Uniform Circular Motion

Uniform circular motion describes the motion of an object traveling at a constant speed along a circular path. Even though the speed remains constant, the direction of the velocity vector continuously changes, which results in acceleration.

Centripetal Acceleration

Centripetal acceleration is the acceleration directed toward the center of the circular path that keeps an object moving in a circle. It is given by the formula a = v²/R, where v is the speed and R is the radius of the circle.

Tangential Acceleration

Tangential acceleration refers to the rate of change of the speed along the circular path. In uniform circular motion, since the speed is constant, the tangential acceleration is zero.

Vector Addition of Acceleration Components

In non-uniform circular motion, the total acceleration is the vector sum of the tangential acceleration and the centripetal (radial) acceleration. The direction of the total acceleration relative to the radial direction is determined by the relative magnitudes of these two perpendicular components. When the tangential acceleration is zero, the total acceleration equals the centripetal acceleration and is directed entirely radially inward.
