Given s=16t^2 where s=distance in feet travelled (downwards) since airborne with zero vertical velocity and zero air-resistance t=time in seconds after release
Here we're given s=144 feet => s=144=16t^2 => t^2=144/16=9 so t=3 Ans. after 3 seconds, the object hits the ground 144 ft. below.
<span>the complete question in the attached figure </span> The answer is the option A 9.9 grams because the balance is accurate to the nearest 1/10 gram; thus, the <span>highest level of accuracy appropriate to the limitations of the balance is 0.10 gram (1/10)</span>
To find how much cinnamon per pound you first divide the $2.40 by the 3 oz to find how much per ounce...so $2.40/3 = 80 cents. Then u multiply that by the 16 oz to get the amount for 1 pound...so .80x16= $12.80 per pound. Hope it helps!
