Okay, then ask an answer!
:) Hope this answers your question :)
It would be: a = v₂-v₁ / t
a = (70-10) / 12
a = 60 / 12
a = 5 m/s²
So, option A is your final answer.
Hope this helps!
Answer:
-6
Step-by-step explanation:
Answer:


let us first take a look at the values of the trigonometric ratios given in the question so that we get quite clear about what is to be done.
here ,

now ,
we just have to plug in the values considering certain other things given in the question and we're done!
so let's start ~

hence , proved ~
