Area= 1/2 base x height
Area= 1/2 8x5
Area= 40/2
Area= 20cm^2
the vertical component of the casting velocity will be reduce to zero at point h by the force of gravity.
If we use the kinematic equation
vf² = vi² +2as
and realize that the final vertical velocity is zero
and the initial vertical velocity is vsinθ
where θ is the angle of cast above the horizon
0 = vsin25 + 2(-9.8)h
h = 0.423v / 19.6
h = 0.02156v
so the missing potential heights and the associated answer velocities are
v = 19 m/s...h = 0.410 m
v = 8.3 m/s...h = 0.179 m
v = 6.9 m/s...h = 0.149 m
v = 8.4 m/s...h = 0.181 m
choose the one that fits the question
or use the method to find the correct velocity based on the actual height reference frame.
It will jut be blank im guessing because if one is blank of one of one hundred it will just be blank
18 is the lowest common multiple 6,12,18 9,18
Answer:
S = 1/2 . x^2 + 11/2 . x + 15
Step-by-step explanation:
- Let S = the area of the shaded region
- From the figure we see that S = 1/2 the area of the rectangle
- The area of the rectangle is (x+5)(x+6) = x^2 + 11x + 30
--> S = 1/2 (x^2 + 11x + 30)
--> S = 1/2 . x^2 + 11/2 . x + 15
