How much work does it take to raise a #25 kg # weight #14 m #?

Answer 1

It takes #"3400 N"# to raise the 25-kg body to a height of 14 m

#"Work"="force"xx"distance"#

The weight in Newtons is the force in this instance.

#"Force"_"weight"=mxxg=25"kg"xx9.81"m/s"^2="245 N"# (I will round the final answer to two significant figures at the end.)

#"Work"=245"N"xx14"m"#

#"Work"=3400"N·m"=3400"Joules"# (rounded to two significant figures)

To calculate the work done, you can use the formula: work = force × distance. The force required to lift the weight is equal to its mass multiplied by the acceleration due to gravity (9.8 m/s^2). So, the force = mass × gravity = 25 kg × 9.8 m/s^2 = 245 N. Now, plug in the values into the formula: work = force × distance = 245 N × 14 m = 3430 J. Therefore, it takes 3430 joules of work to raise a 25 kg weight 14 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.
