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:

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
