Answer:
Its C boys
Step-by-step explanation:
I graphed all of them and compared
Time while going up = time while going down.
One-way time = 0.47 / 2 = 0.235 s
While going up,
s = ut + 1/2 at²; where u is the initial velocity upwards and a is the acceleration due to gravity downwards.
2.14 = u(0.235) + 1/2 x -9.81 x (0.235)²
u = 10.2 m/s
Max height attained can be obtained by:
2as = v² - u²; where v is 0
s = -(10.2)² / -9.81 x 2
s = 5.30 m
The height above the window is:
5.30 - 2.14
= 3.16 m
Answer:
37.5 I think
Step-by-step explanation:
Answer:
2.765 miles
Step-by-step explanation:
Speed = 6 mph = 6 mile per hour
Time = 27:39, which means 27 minutes and 39 seconds.
So in order to find the distance Parker ran, first we need to convert this time to hours.
There are 60 minutes in 1 hour and 60 seconds in 1 minute. So to convert minutes to hour, we divide the by 60. To convert seconds to hour we divided them by 60 twice, once for converting them to minutes and then to second.
So,
27 minutes and 39 seconds =
hours
Since, Distance is defined as:
Distance = Speed x Time
The distance hat Parker ran would be:
Distance =
miles
This means Parker run for 2.765 miles
I believe in standard form this would be 31/2 + 27i/2
