A projectile is projected from the origin with a velocity of 30
1 answer:
For this we will use kinematic equations.
We need the time of flight to compute the range.
With the given information, the most useful formula is:
Δy=v0yt−g2t2
Because our equation is taking only vertical motion into account,
v0y=30sin(45)
Because we are looking for the range of the object,
Δy=0
This leaves us with only one unknown: t
0=30sin(45)t−g2t2
g2t2=30sin(45)t
g2t=30sin(45)
t=60gsin(45)
For horizontal distance, the formula we need is:
Δx=v0xt
Because we are taking into account the horizontal range,
v0x=30cos(45)
In substituting our derived values into the equation we can see that:
Δx=30cos(45)∗60gsin(45)
Range=30cos(45)∗60gsin(45)

Answer:
Each ticket is $43.20
Explanation:
If there are five family members, and the meals are $.6.50 each, we will multiply $6.50 by 5.
$6.50 × 5= $32.5
Now we subtract the meals from the total of $248.50.
$248.50 - $32.5= $216
All five tickets cost $216, now we divide this by 5 since five tickets were bought.
= $43. 2
Each ticket was $43.20
Let's double-check:
$32.5 + $43.20(5)= $32.5 + $216= $248.50
