I’m pretty sure it would take 2hrs but I’m not completely sure but I think
Answer:
At 1.5 seconds and 2.5 seconds
Step-by-step explanation:
Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.
Set that equal to 0 and factor to solve for t:
Using the quadratic formula, we get t = 1.5 and t = 2.5
Is this the full question that is stated?
Answer:
15771 > - 7
Step-by-step explanation:
Comparing the elevation of the two points ;
Point with elevation of 15771 is positive meaning it occurs above sea level and this higher than the point with an elevation of - 7 which is occurring below sea level
Hence, to compare both elevations :
Montblanc has higher elevation than Rhone river delta
Montblanc elevation > Rhone river delta
15771 > - 7
