Question

What is the acceleration of an object if it goes from a velocity of +25 m/s to rest in 5.0 s?
A. –5 m/s2

B. +5 m/s2

C. –25 m/s2

D. +25 m/s2

Answer 1

(final velocity - initial velocity)
--------------------------------------
(final time - initial time)


= ( 0 - 25 ) m/s / ( 5.0 - 0 ) s

= -25/5

= -5 m/s^2

Answer 2
