The power supplied by a machine will always be the power sup

The power supplied by a machine will always be the power supplied to the machine. less than equal to greater than A or B A car is traveling a level road at 88 ft/s. The power being supplied to the wheels is 52,800 ft middot lb/s. find the combined friction force on the tires. 8.82 lb 400 lb 600 lb 4.46 Times 10^6 lb

Solution

1. power supplied by a machine is always greater than power supplied to the machine

2. we know that power = force * velocity

here force nothing but frictional force

therefore force= 52800/88 = 600lb
