Question

A man is running on the straight road with the uniform velocity of 3m/s. Calculate acceleration.​

Answer 1

Statement:

A man is running on the straight road with the uniform velocity of 3 m/s.

To find out:

Acceleration produced by the man.

Solution:

• Given, the man is running with uniform velocity of 3 m/s.
• So the velocity did not change.
• It remains constant.
• We know, acceleration is the change of velocity per unit time.
• Since there is no change in velocity in this case, so there will be no acceleration.
• So, the acceleration produced by the man is zero.

Answer:

The acceleration produced by the man is zero.

Answer 2

Answer is zero

Step-by-step explanation:

Acceleration is defined as the rate of change in velocity. If there’s no change in velocity, then the rate of change is zero, hence the acceleration is zero. The question says the man is running at a uniform velocity (i.e. he’s running at a steady speed in a fixed direction). This means his velocity is constant, or unchanging. Hence, his acceleration is zero.
