Question

Suppose you increase your walking speed from 7 m/s to 15 m/s in a period of 3 s. What is your acceleration?

Answer 1

accelerate = change in v / t

= 15-7/ 3
= 2.6'm/s

Answer 2

here,

youro,

Initial velocity = 7m/s
final Velocity=15m/s

Time taken =3s


the rate of change of Velocity=(15-7)m/s/3
=8/3
=2.6 M/S^2
approx


thanks
