Step-by-step explanation:
We have, Sorin hits a cricket ball straight up into the air. After 1.5 s, the ball is falling straight down with a speed of 6.5 m/s.
We want to find the initial vertical velocity of the ball.
The relation between initial speed, final speed, acceleration and time is given by using first equation of kinematics. Let v₀ is the initial speed. So,
Here, v = -6.5 m/s, t = 1.5 s and a = -g
So, the initial velocity of the ball is 8.2 m/s and the formula used is (1).

unless it's not a prank or a joke question
We are given
A computer downloads a 5-minute video at a constant rate
and we know that
slope is rate of change of date per unit time
and it is changing at a constant rate
so, that constant rate will be slope
and we know that that rate is speed of downloading
so, slope is speed of downloading...........Answer
Use the distance formula!
d = square root of (x2-x1)^2 + (y2-y1)^2
=19.4165
