Question

The position co-ordinates of an object are given by x = 2t2, y = t2 – 4t. The average velocity of particle in first 1 s is

Answer 1

Answer:

The average velocity of the particle is √24 m/s.

Explanation:

Given that,

The position coordinates of an object are

...(I)

....(II)

.....(III)

Time t = 0.1 sec

The velocity is the rate of change with the time of position of an object.

For x coordinate,

Put the value of t in the equation

For y coordinate,

Put the value of t in the equation

For z coordinate,

The average velocity is defined as,

Hence,  The average velocity of the particle is √24 m/s.
