Explanation:
Its translational kinetic energy is:
KE = ½ mv²
It's rotational kinetic energy is:
RE = ½ Iω²
For a solid sphere, I = ⅖ mr², and since it's not slipping, ω = v/r.
RE = ½ (⅖ mr²) (v/r)²
RE = ⅕ mv²
Therefore, the translational kinetic energy is larger.
1. stone
s=9,5m
a=g≈10m/s²
t1=?
s=(at²)/2
2s=at²
2s/a=t²
t=√(2s/a)=√(2*9.5m/10m/s²)=√(1,9s²)≈1,38s
2. sound
s=9,5m
V=343m/s²
t2=?
V=s/t
Vt=s
t=s/V=9,5m/343m/s≈0,03s
-------------------------------------------------
V1+V2=1,38s+0,03s=1,41s
