A) How long did it take for Jason to reach his maximum height? -b/2a=-16/-32= 1/2s
B) What was the highest point that Jason reached?
484ft ~h(ois)
C) Jason hit the water after how many seconds?
roots -5&6 so 6s
Oh and by the way there is some seriously cool cliff jumps in Acapulco, I'm dying to go.
<u>1/2s, 484ft, 6s</u>
Answer:
13≥x U x≥65
Step-by-step explanation:
For a customer to have the reduced movie price tickets, they have to be 13 or younger, or 65 or older so I made the inequality, (X is less than or equal to 13) Union (X is greater than or equal to 65)
Question did not specify that bus was stationary at any point.
60 km/h = 60000/3600 m/s = 16.67 m/s
Shortest time to travel = distance / speed = 1000/(50/3)=60 sec. = 1 min.
If we assume bus was stationary at each stop (if passengers have to get on/off), then acceleration is involved.
Note: at 2 m/s, the bus accelerates from stationary to 60 km/h in 8 seconds!
Using kinematics equation
2aS=v^2-u^2
we have
a=acceleration = 2m/s
S=distance
u=0 initial speed
v=final speed=50/3 m/s=60 km/h
Distance travelled = (v^2-u^2)/(2a)=(50/3)^2/(2*2)=625/9 m=69.33 m.
Remaining distance at 60 km/h
=1000-69.44-69.44=861.11 m
time to travel = 861.11/(50/3)=51.67 s.
Time to accelerate/decelerate= (50/ 3)/2 m/s / m/s^2 = 8.333 s.
Total time = 51.67+2*8.33=68.33 s.
I think it is 3 because of PEMDAS but otherwise it might be 2
