Answer:
The ball reaches 44 ft above the ground after 4 sec.
Step-by-step explanation:
Set h(t)=-16t^2+300 equal to 44 feet and solve for time, t. Indicate exponentiation with " ^ "
-16t^2 + 300 = 44 becomes
-16t^2 + 256 = 0, or 16t^2 = 256. Then, taking the square root of both sides, we get:
4t = 16, or t = 4 sec. The ball reaches 44 ft above the ground after 4 sec.
You could sit down with several pencils and a whole pad of paper, and
divide Leda's mass by Europa's mass. But it's probably good enough
to provide an answer that's correct to 2 or 3 significant figures, and
there's a much easier way to do that:
Leda's mass . . . . approx. 1.094 x 10¹⁶
Europa's mass . . . . approx. 4.8 x 10²²
Leda's mass is about (1.094 x 10¹⁶) / (4.8 x 10²²) of Europa's mass.
(1.094 x 10¹⁶) / (4.8 x 10²²) = 2.28 x 10⁻⁷
Leda's mass is approx. <em>0.000 000 228</em> of Europa's mass.
