20 | 76.9 | 4ft |
25 | 87.7 | 4ft |
30 | 97.6 | 4ft |

work calculations
(work = newtons x meters)

Explanation:

Step1: Convert feet to meters

We know that 1 foot = 0.3048 meters, so 4 feet = \(4\times0.3048 = 1.2192\) meters.

Step2: Calculate work for 5 washers

Work formula: \(W = F\times d\), where \(F = 21.7\) N, \(d = 1.2192\) m.
\(W_1=21.7\times1.2192\approx26.46\) joules.

Step3: Calculate work for 10 washers

\(F = 50.8\) N, \(d = 1.2192\) m.
\(W_2 = 50.8\times1.2192\approx61.93\) joules.

Step4: Calculate work for 15 washers

\(F = 65.3\) N, \(d = 1.2192\) m.
\(W_3=65.3\times1.2192\approx79.61\) joules.

Step5: Calculate work for 20 washers

\(F = 76.9\) N, \(d = 1.2192\) m.
\(W_4 = 76.9\times1.2192\approx93.75\) joules.

Step6: Calculate work for 25 washers

\(F = 87.7\) N, \(d = 1.2192\) m.
\(W_5=87.7\times1.2192\approx106.92\) joules.

Step7: Calculate work for 30 washers

\(F = 97.6\) N, \(d = 1.2192\) m.
\(W_6=97.6\times1.2192\approx119.00\) joules.

Answer:

Number of Washers	Weight (N)	Distance (m)	Work (J)
10	50.8	1.2192	~61.93
15	65.3	1.2192	~79.61
20	76.9	1.2192	~93.75
25	87.7	1.2192	~106.92
30	97.6	1.2192	~119.00

(If you only need the work values calculated: For 5 washers: ~26.46 J, 10 washers: ~61.93 J, 15 washers: ~79.61 J, 20 washers: ~93.75 J, 25 washers: ~106.92 J, 30 washers: ~119.00 J)
