rose is sledding down an ice covered hill inclined at an angleof 15degrees with the horizontal. if rose and the sled have acombined mass of 54.0 kg, what is the force pulling themdown. i know to mulitply 54(9.8) the gravity to get newtons but whatdo i do next. rose is sledding down an ice covered hill inclined at an angleof 15degrees with the horizontal. if rose and the sled have acombined mass of 54.0 kg, what is the force pulling themdown. i know to mulitply 54(9.8) the gravity to get newtons but whatdo i do next.

Explanation / Answer

mass m = 54 kg angle = 15 degrees required force F = mg sin                          = 54 * 9.8 * sin 15                          = 136.96 N
