Here are the solutions to the work done questions, worked out step by step.
1. Formula Triangle
The formula is:
Work Done = Force × Distance.
In a formula triangle, the two things being multiplied go at the bottom, and the result goes at the top.
*
Top: Work done (J)
*
Bottom Left: Force (N)
*
Bottom Right: Distance (m)
2. Arsene Wenger
*
Given: Force = 60 N, Distance = 10 m.
*
Formula: Work = Force × Distance.
*
Calculation: $60 \times 10 = 600$.
*
Answer: 600 J
3. Philip Schofield
*
Given: Force = 200 N, Distance = 0.5 m.
*
Formula: Work = Force × Distance.
*
Calculation: $200 \times 0.5 = 100$.
*
Answer: 100 J
4. Kim Kardashian
*
Given: Work (Energy) = 100 J, Force = 150 N.
*
Formula: We need to find Distance, so we divide Work by Force ($Distance = Work / Force$).
*
Calculation: $100 / 150 = 0.666...$
*
Answer: 0.67 m (rounded to 2 decimal places)
5. Olly Murs
*
Given: Force = 2.5 kN, Distance = 2.5 m.
*
Step 1: Convert kilonewtons (kN) to newtons (N). Since $1 \text{ kN} = 1000 \text{ N}$, then $2.5 \text{ kN} = 2500 \text{ N}$.
*
Step 2: Calculate Work. $Work = 2500 \times 2.5$.
*
Calculation: $2500 \times 2.5 = 6250$.
*
Answer: 6250 J
6. Beyonce
*
Given: Work (Energy) = 3000 J, Force = 1.5 kN.
*
Step 1: Convert force to Newtons. $1.5 \text{ kN} = 1500 \text{ N}$.
*
Step 2: Find Distance. $Distance = Work / Force$.
*
Calculation: $3000 / 1500 = 2$.
*
Answer: 2 m
