The time taken for the particle to travel more than 8 meters from the point of projection is 0.59 s.
<h3>
Time of motion of the particle</h3>
The time taken for the particle to travel more than 8 meters from the point of projection is calculated as follows;
s = v₀t + ¹/₂at²
8 = 12t + (0.5 x 5)t²
8 = 12t + 2.5t²
2.5t² + 12t - 8 = 0
solve the equation using formula method
t = 0.59 s
Thus, the time taken for the particle to travel more than 8 meters from the point of projection is 0.59 s.

Answer:
245 cm²
Step-by-step explanation:
The surface area of a cone is given by ...
SA = πr(r +s) . . . . where r is the radius, and s is the slant height
Filling in the given values, we have ...
SA = (3.14)(3 cm)(3 cm +23 cm) = (3.14)(3)(26) cm² ≈ 245 cm²
The surface area of the cone is about 245 cm².
