Question

if a girl is running along a straight road with a uniform velocity 1.5m/s,find her acceleration

Answer 1

Answer:

acceleration is the rate of change of velocity

so if velocity is not changing that is uniform then acceleration is obviously zero

Answer 2

Answer:

I hope it's helpful please mark me as brainliast

Explanation:

she has zero acceleration along the road. However, she has to move her legs in order to run, so probably her center of gravity rises a little and falls a little at each step. If this is the case, if you attach an accelerometer to her, it will measure a small cyclic acceleration in the vertical direction.

Acceleration is zero because the girl is running with constant velocity.
