two sleds are hooked together in tandem as shown in the figure. the front sled is twice as massive as the rear sled. the sleds are pulled along a frictionless surface by an applied force . the tension in the rope between the sleds is . determine the ratio of the magnitudes of the two forces, .

Consider motion in one dimension. (the sign of the vector quantities is their direction indicator.) an object moves in the positive x-direction with speed 2.9 m/s for 4.5 s. it stops for 3.8 s and then moves in the negative x direction with speed 2.8 m/s for 4 s. what is the total distance traveled by the object in units of meter? enter a number with two digits behind the decimal point.
