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).

Answer and step-by-step explanation:
Tim Carter money made:
First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)
Because he works for 50 hours so next 10 hours (50-40) = 10 * (1.5*5.15)
= 10* 7.725 = $77.25
Total money he made:
= 206 + 77.25 = $283.25
Jeese Jones money amde:
First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)
Because he works for 47.5 hours so next 7.5 hours (47.5-40) = 7.5 * (1.5*5.15)
= 7.5 *7.725 = $57.9375
Total money Jeese Jones made:
= 206 + 57.9375 = $263.9375
Barbara Burns money made:
First 40 hours = 40 * pay per hour = 40 * 5.15 = $206 (weekly pay)
Because Barbara Burns works for 44 hours so next 4 hours (44-40) = 4 * (1.5*5.15)
= 4* 7.725 = $30.9
Total money Barbara Burns made:
= 206 + 30.9 = $236.9
Hope this help you :3
