# Which has more momentum, a 8kg object moving at 4m/s or a 7kg object moving at 5m/s?

May 26, 2018

Object having mass $8 k g$ has more momentum.

#### Explanation:

Momentum is given by product of mass and velocity.
So, $p = m \times v$

Momentum of object having mass $8 k g$ $= 8 \times 4$

Momentum of object having mass $8 k g$ $= 32 k g m {s}^{-} 1$

Momentum of object having mass $7 k g$ $= 7 \times 5$

Momentum of object having mass $8 k g$ $= 35 k g m {s}^{-} 1$

Hence, Object having mass $8 k g$ has more momentum.
