Answer:
6.7 seconds
Step-by-step explanation:
Let's calculate the maximum height covered by the object
Max height= U²Sin²tita/2g
Where g is acceleration due to gravity
Max height= 40²(sin90)²/(2*9.81)
Max height= 1600/19.62
Max height=81.55 m
Total max height= 30+81.55
Total max height= 111.55 m
Time t it will take to travel from the max height at acceleration of 4.9 m/s²
S= ut + ½at²
u= 0 at Mac height
S= 111.5 m
111.5 = ½(4.9)t²
223/4.9= t²
45.5= t²
6.745 seconds= t
6.7 seconds= t
Answer:
$82.65
Step-by-step explanation:
First, find the cost with the discount:
78.72(0.85)
= 66.91
Then, find the amount of the tip:
78.72(0.2)
= 15.74
Then, add together the cost and tip:
66.91 + 15.74
= 82.65
So, the total cost of the meal was $82.65
