12 A car is on a driveway that is inclinded 25 to the horizo

12.) A car is on a driveway that is inclinded 25° to the horizontal. If the car weighs 2675lbs, find the force required to keep it from rolling down the driveway.

Solution

Mass of car in kgs = 2675*0.453 = 1213.36 kg

Weight = 1213.36*9.81 = 11903.0616 Newton

Car is on driveway which is inclned at 25 deg

So, compoennt of weight of car horizontal of plane = force required to keep it from rolling down the driveway.

force required to keep it from rolling down the driveway. = 11903.0616*sin25 = 5030.45 Newton
