Infinite campus has two options for one it’s the instruction
Density=mass/volume
mass= 5kg
volume: πr²h
= π(2)²(5)
=62.83 cm³ or 0.06283 m³
density: m/v
d= 5/0.06283 m³
d=79.57 kg/m³
Hope I helped :)
Answer:
20.65 m/s
Explanation:
You are gonna wanna use a calculator for this one
so we will write all the known variables:
h = 15.6 m
initial velocity (u) = 10.7 m/s
acceleration (a) = 10 m/s/s (gravity)
From the third equation of motion:
<em>v² - u² = 2ah</em>
<em>v² - (10.7)² = 2(10)(15.5)</em>
<em>v² - (10.7)² = 312</em>
<em>v² = 312 + 114.49</em>
<em>v² = 426.49</em>
v = 20.65 m/s
