Answer:

a). 675J

b). 337.5J

c). 1012.5J

Explanation:

M = 6.0kg

V = 15.0m/s

a). Translational energy

E = ½ *mv²

E = ½ * 6 * 15²

E = 675J

b). Rotational kinetic energy K.E(rot) = Iw²

But moment of inertia of a cylinder (I) = ½Mr²

I = ½mr²

V = wr, r = v / w

K.E(rot) = ¼ mv²

K.E(rot) = ¼* 6 * 15²

K.E(rot) = 337.5J

Total energy of the system = K.E(rot) + Translational energy = 337.5 + 675

T.E = 1012.5J

erma4kov [3.2K]

Answer:

2,400kg * m/s

Explanation:

You are missing some information in the question but the rest could be found some where else.

The question gives the masses and starting velocity of each car.

Car 1: m = 600kg and sv = 4m/s

Car 2: m 400kg and sv = 0m/s

Find the momentum of both cars.

Car 1: 600 * 4 = 2400

Car 2: 400 * 0 = 0

Add both.

2400 + 0 = 2400

Best of Luck!
