The momentum of an object is determined to be 7.2 x 103 kg m/s

The momentum of an object is determined to be 7.2 x 103 kg · m/s. Express this quantity as provided or use any equivalent unit. (Note: 1 kg = 1000 g).

Solutions

Expert Solution

Momentum = 7.2 × 10-3kg.m/s

= 7.2 × 10-3 ×1000 g × 100 cm/s

= 7.2 × 102 g.cm/s

Expert Solution

The momentum in g.m/s is:

$$\begin{array}{l}p = 7.2 \times {10^{ - 3}}kg.m/s\\p = \left( {7.2 \times {{10}^{ - 3}}kg.m/s} \right) \times \left( {\frac{{1000g}}{{1kg}}} \right)\\p = 7.2g.m/s\end{array}$$

The momentum in g.cm/s is:

$$\begin{array}{l}p = 7.2 \times {10^{ - 3}}kg.m/s\\p = \left( {7.2 \times {{10}^{ - 3}}kg.m/s} \right) \times \left( {\frac{{1000g}}{{1kg}}} \right) \times \left( {\frac{{100cm}}{{1m}}} \right)\\p = 720g.cm/s\end{array}$$
