g to be assumed to be 10m/s
A car of mass 800kg is towing a trailer of mass 400kg up a hill of inclination x where sinx = 1/20. The trailer is connected to the car by a towbar which is parallel to the direction of hte motion. At a given instance, the speed of both vehicle is 7m/s and both accelerating at 0.1ms-2. At this instance the power of the car engine is 14KW and the resistance to the motion of the car is 300N.
Show the tension in the tow bar is 1220 N
Resistance to the motion of the trailer..
Im all confused, i dont seem to understand the concept of tension at all....
I know P = f s
so that gives me 14 000/7 = 2000 N
But it's on an inclined surface so i guess you gotta do something to it...
considering the resistance is 300N so gotta subtract it right ?
giving me 1700 N ?
