Answer:
A. Its translational kinetic energy is larger than its rotational kinetic energy.
Explanation:
Given that
Radius = R
Mass = M
We know that mass moment of inertia for the solid sphere

Lets take angular speed =ω
Linear speed =V
Condition for pure rolling , V= ω R
Rotation energy ,RE





RE= 0.2 MV²
The transnational kinetic energy TE

TE= 0.5 MV²
From above we can say that transnational energy is more than rotational energy.
Therefore the answer is A.
Answer:
one for physical is that your muscles will seize up or cramp when you try to move. one for mental is that if your always sitting down you will most likely become stressed or get depression

Answer:42.43m/s
Explanation:According to vf=vi+at, we can calculate it since v0 equals to 0. vf=0+9.8m/s^2*4.33s= 42.434m/s
When hockey players push the puck along the ice it slides causing heat which melts the ice causing the friction against the ice to be less.
