Answer:
you can't go ice skating on it because if it just reached the temp then you need to wait for about 2 hours
Explanation:
Answer:42.4m/s^2
Explanation:
Velocity(v)=6m/s
Radius(r)=0.85 meter
Centripetal acceleration=(v x v) ➗ r
Centripetal acceleration=(6 x 6) ➗ 0.85
Centripetal acceleration=36 ➗ 0.85
Centripetal acceleration=42.4
Choice-'b' says the formula for kinetic energy in words.
KE = (1/2) · (M) · (S²)
