The total kinetic energy will be equivalent to the potential energy;
The total kinetic energy is given by the sum of transitional kinetic energy and the rotational kinetic energy.
Rotational kinetic energy
I= 1/2mR², but rotational energy =1/2 I w² 
Thus  rotational energy is equal to 1/4 mR²w², which is equivalent to 
 = 1/4 mv² since v= wR
Thus;
Total kinetic energy = 1/2 mv² + 1/4 mv²
hence;
 Mgh = 3/4 mv²
  gh = 3/4 v² ( assuming g = 9.81 m/s²)
   72.1035 = 3/4 v²
v = 9.805
    = 9.805 m/s

Collision Problem. Need help!
lukranit [14]

Answer:

4 Km/hr

Explanation:

Data obtained from the question include the following:

Mass of ball (Mb) = 15 Kg

Velocity of ball (Vb) = 20 Km/hr

Mass skater (Ms) = 60 Kg

Velocity of skater (Vs) = 0 Km/hr

Velocity after collision (V) =..?

Thus, we can obtain the velocity after collision as follow:

MbVb + MsVs = V(Mb + Ms)

(15 x 20) + (60 x 0) = V (15 + 60)

300 + 0 = 75V

300 = 75V

Divide both side by 75

V = 300/75

V = 4 Km/hr.

Therefore, the velocity after the collision is 4 Km/hr.
