Question

a body moving with a velocity 'u' covers a distance of 20m in 10 s with a uniform velocity what is the acceleration of the body also mention the direction​

Answer 1

Explanation:

Suppose the acceleration is a then using the second equation of motion, s=ut+

2

1

at

2

and putting t=2sec and u=10m/s

we get 20=10×2+a×2

or a=0 that is uniform motion.

Answer 2

The acceleration of the given body is equal to zero.

• Acceleration of a body is the rate of change of its velocity.
• Here, in this case, the velocity of the body is mentioned to be uniform i.e. constant.
• So the rate of change of velocity is zero.
• Hence, the acceleration of the body is zero.
