Answer 2

Answer:

60 m/s

90000 J

Explanation:

We have,

=> Mass (m) = 50 Kg

=> Momentum (p) = 3000 Kg.m/s

To find,

=> Velocity (v)

=> Kinetic energy (K.E)

Solution,

Momentum(p) = mass(m) × velocity(v)

=> 3000 = 50 × v

=> v = 3000/50

=> v = 60 m/s

Kinetic energy = 1/2 × mass × velocity²

=> K.E = 1/2 × 50 × 60²

=> K.E = 25 × 3600

=> K.E = 90000 J
