in a tug of war a jeep of a mass 1400kg and a tractor of a mass of 2000kg pull on a horizontal rope in opposite directions. at one instant, the tractor pulls on the rope with a force of 1.50*10^4N while its wheels push horizontally against the groud with a force of 1.60*10^4N Calculate the instanous accelerations of the tractor and of the jeep and also calculate the horizontal push of the wheels of the jeep on the ground.

Answer 1

Net force=ma
1.60E4-1.50E4=(1400+2000)a
solve for a. Remember, the vehicles are attached, both masses are moved by the same net force.

Answer 2

do you go to SPS

Answer 3

yeah i do go to sps hahaah

Answer 4

A girl pulls a sled along a level dirt road by means of a rope attached to the front of the sled. The mass of the sled is 40kg the coefficient of friction is. 600, and the angle between the rope and the road is 30 degrees. What pull must the girl exert to move the sled at constant velocity?
