Answer: 1608.39 J
Explanation: Given that the
mass M = 42kg
U = 11.5m/s
V = 3.33m/s
how much work did friction do
Work done = Force × distance
Work done = Ma × distance
But acceleration a = V/t
Work done = M × V/t × d
Work done = M × V × d/t
Where d/t = velocity
Therefore,
Work done = M × U × V
Work done = 42 × 11.5 × 3.33
Work done = 1608.39 J
the independent variables are the different
laudry detergent
the dependent variable is color of the cloth
after washing
the control variables are the amount of water
added and by washing one cloth b just water
<span>hypothesis: the cloth washed with laundry
