Answer:
The answer to your question is: is = 14 m/s
Step-by-step explanation:
Data
acceleration = 2 m/s² = a
final speed = 20 m/s = sf
time = 3 seconds = t
initial speed = ? = is
Formula
sf = is + at
is = sf - at
Substitution
is = 20 - (2)(3)
is = 20 - 6
is = 14 m/s
Answer:
.53655265
Step-by-step explanation:
Well i ll give u some tips
1-u should know the formulas for calculating different objects areas
2-find the length of their sides or diagonals(which are needed on the formula)
3-calculate the area
for example the triangle on the picture
1-s=leg1*leg2/2
2-the length of:leg1=10-3=7,,leg2=7-1=6
3-s=7*6/2=21
