Question

Answer Problems 3 through 5 by choosing one of the eight labeled acceleration vectors or selecting option

$\text{I}:\overrightarrow{a}=\overrightarrow{0}$

3. At this instant, the particle has steady speed and is curving to the right. What is the direction of its acceleration?

Short answer

The acceleration of the particle at that instant is zero.

Step-by-step solution

Step 1. Introduction

The particle is having steady speed and curving to the right.

Formula to calculate the instantaneous acceleration of a particle is,

$\overrightarrow{a}=\frac{dv}{dt}$-$\overrightarrow{a}$ is the instantaneous acceleration of the particle at the give instant.

$\frac{dv}{dt}$- is the change in velocity of the particle at that instant.

Step 2. Explanation

The particle is having steady speed, so the change in velocity of the particle at any instant is zero. Thus, the acceleration of the particle at that instant is zero.

Therefore, the acceleration of the particle at that instant is zero.
