From the calculations;
- The highest point above the ground is 112 feet
- The time taken to reach this height is 8 seconds
<h3>Equations of motion</h3>
The equations of motion are used in kinematics to obtain the various variables that has to do with motion.
In this case;
distance covered = 30 ft
initial velocity = 40 ft/second
Final velocity = 0 m/s at the maximum height
Hence;
v^2 = u^2 - 2gh
since v = 0
u^2 = 2gh
h = u^2/2g
h = (40)^2/2(9.8)
h = 82 feet
highest point above the ground = 82 feet + 30 feet = 112 feet
Now;
v = u - gt
since v = 0
u = gt
t = u/g
t = 40/9.8
t = 4 seconds
Time taken to hit the ground = 2(4 seconds) = 8 seconds

Ok 4.56 * 0.08 is 4.56 * 8 / 100
4.56* 8 is 45.60 - 9.12 because times by ten then minus times by 2 = 36.48
divide by 100 is 0.3648 then times to get in pence so 37 pence is tax on the item

Answer:
SU= 14
Step-by-step explanation:
if QU= 24 and RU= 19 then you can subtract 24-19=5. and if QR=RS=ST then you subtract 19-5=14
