Question

Can anyone help me with this physics motion chapter's question...... Plzzzzz.. Its really important......... ​

Answer 1

Answer:

B.Uniform Acceleration

C.At DE,

              a=10-5÷10-8

              a= -2.5m/s²

D. In general CE refers to uniform acceleration.

             

Explanation:

A.First of all where is the point O?

B. As the V-t graph gives us acceleration thus straight line of V-t graph gives us Uniform or Constant motion.

C. Retardation is present only at point DE.

D.Considering D point between CE then first increasing acceleration is present i.e. at CD ,then retardation is present at DE. In general CE refers to uniform acceleration.
