Two girls pull a 15 kg sled, each with her own rope. they pull horizontally at an angle of 30 degrees from each other with identical forces of 27 n each. the coefficient of friction between the snow and the sled is 0.1. the acceleration of gravity is 9.8 m/s 2 . what is the acceleration of the sled?

The acceleration of the sled

Explanation:

Using Newton's law the force the tow girls are making pulling the sled get an acceleration so:

However the forces make the system in equilibrium and can find the force total os the system to find the acceleration of the system

∑F=F=0

∑F=Fj=0

The force F1 is in the same axis so the F2 have component in axis 'y' and F1 in axis 'y' is zero

The total force is in axis 'x' so:

magnityde and direction

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
