Answer:
Momentum after = 2400 kgm/s
Explanation:
Momentum after = momentum before
Momentum after = m1v1 +m2v2
Momentum after = (600)(4) + (400)(0)
Momentum after = 2400 kgm/s
A motor takes in electricity from a cell or power source and then uses it to move components.
Therefore the answer is (1) Electrical to Mechanical
