Divide the amount of Newtons by 9.8. So if you have [300N====>kg] you would divide 300/9.8 to give you 30.6kg.
We must assume that Susie's weight was recorded on earth. Since she weighs 300N on earth, her mass is 30.61 kilograms. If her weight had been 300N somewhere else, like on Mars or the moon, it would mean that her mass is some different figure.

The resultant is what you get when you add together all the vectors. You only listed one vector, so the sum of all of it is the same as the one vector. The resultant is 300n at 0 degrees.
Definately 12 volt.

The work done by the man is calculated as the product of the force applied, the distance moved in the direction of the force, and the cosine of the angle between the force and the direction of movement. The work done can be calculated using the formula: work = force * distance * cos(theta), where the force is 300N, the distance is 10m, and the cosine of the angle is typically 1 when the force and displacement are in the same direction. Thus, the work done by the man would be 300N * 10m * 1 = 3000 Joules.
To calculate the effort required, first determine the input force needed to lift the load by dividing the load (300N) by the mechanical advantage (velocity ratio of 5). So, 300N / 5 = 60N. Next, take into account the efficiency of 60%, so the effort required is 60N / 0.60 = 100N.
200 + n = 100 + 200200 + n = 300n = 300 - 200n = 100

From the information given, we know the weight of the cart, but we don't actually knowhow much force the horse has to exert in order to pull the cart.Since the 300N is the only force given in the problem, let's assume that it's the force thehorse has to produce. It's a minuscule force ... only about 67 pounds ... so we can takeour time working on the problem, without worrying too much about overworking the horse.Work = (force) x (distance)Power = (work) / (time) = (force) x (distance) / (time)= (300) (15) / (240) = 18.75 wattsConsidering that the definition of "1 horsepower" is 746 watts, I'm comfortable with the loadwe've put on this particular animal for our academic exercise.
