Step 1
Introduction:
Kinematics helps to find out the velocity, acceleration of the particle at any time t when position of the particle is given. The relation between displacement, velocity and acceleration helps to find the unknown quantity.
Given data:
The position of the particle in the space at time t is,
Where,
t- time
i, j, k unit vectors in the direction of x, y, z axis
Formula used:
The relation between displacement is the, 'velocity is the time derivative of displacement'
Similarly relation between displacement and acceleration is,
Step 2
Calculation:
Velocity of the particle is,
Acceleration of the particle is,
