Step-by-step explanation:
Area of a triangle- 1/2 x h x base
8 x4= 32
32/2= 16
Part A Equation and Solve: (16.2x7) Answer: 113.4
Part B Ribbon: 113.4 x4
Part C Combining: 340.2
Answer:
B) 3
Step-by-step explanation:
4+5+1/3=10/3=3.333~3
Formula is: h = vi · t + 1/2 g · t²
For the final position ( on the ground ): h = - 255 ft
vi = - 21 ft/s, g = -9.81 m/s² = - 32.174 ft/s²
- 255 = - 21 t - 1/2 · 32.174 t²
16.087 t² + 21 t - 255 = 0
t 1/2 = ( - 21 +/- √ (441 + 16,408.74 ))/ 32.174 =
= ( -21+/- 129.8 ) / 32.174 = 108.8 / 32.174 = 3.38 s
Answer: The ball hits the ground after 3.38 s.
