Use the formula ( t = \frac{m \cdot v}{I \cdot V} ), where: ( m = 3 , \text{kg} ) (mass), ( v = 4 , \text{m/s} ) (final velocity), ( I = 7 , \text{A} ) (current), ( V = 3 , \text{V} ) (voltage). Calculate ( t ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
