Question

If 2.0 j of work Is done raising a 180 g Apple how far was it lifted

Answer 1

The apple is lifted by 1.1 m

Explanation:

• Given that, mgh = 2 J and mass of apple = 180g
• Step 1: convert grams to kg as work is given in SI units.

                    180 g = 0.18 kg

• Step 2: substitute in the formula for work done.

                    0.18 * 10 * h = 2

• Step 3: calculate the value of h from this formula.

                      h = 2/1.8

                      h = 1.11 m
