Answer:five times five is twenty five divded by 10 is 2.5 seconds of acceleration
The type of precipitation expected to occur in Florida is "Rain" when the temperatures of air and clouds are above freezing point.
<u>Explanation:</u>
Under certain conditions, water droplets get freezes due to low temperatures. However, if the temperature of the air beneath the cloud is higher than the freezing point 32°F (0°C), the frozen start to meltdown due to high temperature and falls as raindrops on the surface of the earth. Hence Rain form of precipitation is expected to occur in Florida when the temperature of the cloud and air is above freezing.
Answer: 244.05 J
Explanation:
To find speed at 30 m above the ground use equation:
V²=Vo²-2Gs
V0=31.4m/s
s=30m
G=9.81m/s²
-----------------------
V²=31.4²-2*9.81*30
V²=985.96+588.6
V²=1574.56
V=39.68m/s ---speed of arrow on 30 m obove the ground
Use equation for kinetic enrgy:
Ke=mV²/2
m=0.155kg
V=39.68m/s
-------------------------
Ke=0.155kg*(39.68m/s)²/2
Ke=0.155*1574.5/2
Ke=244.05J
