Answer:
0.0605 Kg m^2
Explanation:
In this case where we have find he moment of inertia of this object about an axis perpendicular to the x-y plane and passing through the origin, we can just add three moment of inertia's .
MOI= 0.25×0.3^2 + 0.35×0.4^2- 0.45×0.2^2
= 0.0605 Kg m^2

Answer:
<h3>The answer is 90 m/s</h3>
Explanation:
To find the final velocity of an object given it's initial velocity , time taken and it's acceleration we use the formula
<h3>v = u + at </h3>
where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
From the question
u = 40 m/s
t = 10s
a = 5 m/s²
We have
v = 40 + 5(10) = 40 + 50
We have the final answer as
<h3>90 m/s</h3>
