Question

It took a bulldozer 62,000 J of work to move a rock 30 m. It took 5 minutes. How much force did the bulldozer have to apply?

A- 2066.6 N
B- 413.33 N
C- 12,400 N
D- 10,333.33 N

Answer 1

A (2066,6 N)

Step-by-step explanation:

Use the Work formula

62.000J = F . 30

62.000/30 = 2066,6 N

The amout of time it took to move the rock doesn´t matter at all.

It is called a distraction variable, We don´t need it to solve the problem it is there just to confuse.
