An object moving at 40 m/s takes 10 s to come to a stop. What is the object’s acceleration?

-4 m/s^2

Explanation:

v=vo+at

0=40+a(10)

-40=a(10)

-4=a

We know that,

Acceleration = Change in rate of velocity/time taken.

A = 0 - 40/10

A = - 40/10

A = - 4m/s².

Hence, Negative acceleration or Retar-dation of the object is 4m/s².

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
