Answer
Step-by-step solution
3 stepsIdentify the given values.
The problem states that the tangential acceleration is .
The speed of the particle is .
The radius of curvature of the path is .Calculate the normal (centripetal) acceleration .
The normal acceleration is responsible for changing the direction of the velocity and is given by the formula:
Substitute the given values:
Calculate the total acceleration .
The total acceleration is the vector sum of the tangential acceleration and the normal acceleration . Since these two components are perpendicular to each other, the magnitude of the total acceleration is found using the Pythagorean theorem:
Substitute the values of and :
Rounding to two decimal places, we get:
