How much work does it take to raise a #2 kg # weight #9 m #?

Answer 1

#"176.4 J"#

#"Work = Force × Displacement"#
#"Work = mg × h = 2 kg × 9.8 m/s"^2 × "9 m" = "176.4 J"#

To calculate the work done, you use the formula: Work = Force × Distance. In this case, the force is equal to the weight, which is the mass multiplied by the acceleration due to gravity (9.8 m/s²). So, the force is 2 kg × 9.8 m/s² = 19.6 N. Then, you multiply this force by the distance traveled: 19.6 N × 9 m = 176.4 J. Therefore, it takes 176.4 joules of work to raise a 2 kg weight 9 meters.

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.
