If an object ...

Question

If an object has zero momentum.........wh wh will be it's kinetic energy.........(can the velocity also never be 0)??????

Open in App

Solution

No because momentum is given by mass * velocity.
Since momentum is zero, velocity is zero as object cannot have 0 mass
Hence the kinetic energy will be zero as K.E = 1/2 mv^2
