(3) Calculate in newtons, the weight of a 2000-kg elephant.

To calculate the weight of the elephant in newtons, we need to use the formula:<br /><br />Weight = Mass x Acceleration due to gravity<br /><br />Given information:<br />- Mass of the elephant = 2000 kg<br />- Acceleration due to gravity = 9.8 m/s² (standard value on the surface of the Earth)<br /><br />Substituting the values in the formula:<br /><br />Weight = 2000 kg x 9.8 m/s²<br />Weight = 19600 N<br /><br />Therefore, the weight of the 2000-kg elephant is 19600 newtons.
