When drinking at a private event, you should assume that drinks will be STRONGER THAN NORMAL.
At private events, some hosts have the habit of mixing different drinks together in order to increase the intoxicating power of the drinks.

Reduce friction because friction just makes things harder
Answer:
1.61 second
Explanation:
Angle of projection, θ = 53°
maximum height, H = 7.8 m
Let T be the time taken by the ball to travel into air. It is called time of flight.
Let u be the velocity of projection.
The formula for maximum height is given by
By substituting the values, we get
u = 9.88 m/s
Use the formula for time of flight
T = 1.61 second
The answer would be 20000
The answer in standard form/scientific notation would be 2 x 10^4
(The exponent is 4 because that's how many digits after the 2 there is)
