1. 2+0.5+2.5= 3. 2km/hr average
2. 14-6=4seconds. 8m/s in 4s = 2m/s acceleration
3. 15m/s divided by 2.5 = 6m/s acceleration
Answer:

Answer:
Rain came along with lower temps
Explanation:
There was no rain on the warmer days
There were more clouds as the week went on

Answer: 588.9 m/s
Explanation:
Given that :
θ = 30°
Height, h = 3400m
Time, t = 10 seconds
From trigonometry ;
Tanθ = opposite / hypotenus
Tan 30 = 3400 / x
x tan 30 = 3400
0.5773502x = 3400
x = 3400 / 0.5773502
x = 5888.9727
Recall ;
Speed = Distance / time
Speed = 5888.9727 / 10
Speed = 588.897 m/s
Speed = 588.9 m/s
