![]() ![]() Paying attention to units is a great thing and you are doing that well. But that's pretty much what you have already worked out using the units. Work=Force*Distance, so dividing by unit time gives you Power=Force*Velocity. f horizontal force friction force f 70 10 f 60 NNET force on the body is equal to 60 N. Is this a correct way of doing the problem? Is there another way to do it with an equation and number crunching? direction) is the horizontal basement -10 N (West direction) is the force friction The net force is also knows the mass of the cratem 20 kgso we can nd the acceleration You might be interested in an electric current will exist when it exists a net ow of electric charge through a region. In the end, I use watts equals newtons times velocity and solve for newtons, dividing watts by velocity (in this case, 210 watts divided by 7 meters per second). I know that watts in joules per second is equal to newtons times meters per second, which in turn, becomes newtons times velocity. I'm trying to find force (newtons) when given mass (kilograms), watts (Joules per second), and velocity (meters per second). The way I did this problem was by looking at my units. What average force is exerted eastward on the bicycle to maintain this constant speed?
