Answer:
T²= 4π²R³/GM
Explanation:
First we know that
Fg= Fc
Because centripetal force must equal gravitational force
So
GMm/R² = Mv²/R
But velocity is 2πR/T
So by substitution we have
GMm/R²= M (2πR/T)/T
We have
T²= 4π²R³/GM as period

Answer:
a) 3.9s
b)74m
Explanation:
a) v=u+at
0=38+(-9.8)t
-38=-9.8t
t=-38/-9.8
t=3.877s
t=3.9s
b) s=ut+1/2at²
s=(38×3.9)+1/2(-9.8×3.9²)
s=148.2 -74.529
s=73.671
s=74m
