The first part of the question uses the formula for finding work done, which is
W=F*d, where W is work done in joules, F is the force used in newtons, and d is the displacement in metres. Looking at our question, we see that W=185000 and d=285. Plug these value into the formula, and we get
185000= F * 285
185000/285=F
37000/57=F
649.123N~~F. This the answer to the first part of our question.
The second part of the question uses the formula for finding force put on an object
F=ma, where F is force in newtons, m is the mass of the object in kilograms, and a is the acceleration of the object. We know that F=37000/57, and the acceleration is due to gravity, making a=9.81ms^-2. Plug these values into the equation, and we get
37000/57=m*9.81
37000/57 ÷ 9.81=m
66.17~~m. This is the answer to the second part of our question.
I hope I helped!
