Answer:
i think its 60
Step-by-step explanation:
base times height then divide by 2
according to the picture we have:
x.y=4.7
(7)x(7)y=49xy=(49)(4.7)=230.3
We can find the acceleration via

We have


Then by definition of average acceleration,

so that


We alternatively could have found the time without knowing the acceleration. Since acceleration is constant, the average velocity is

Then


Answer:
square root of five but if it needs to be simplified then 2.24 (rounded)
