I feel like i basically know how to do this question but im not 100% sure(adsbygoogle = window.adsbygoogle || []).push({});

A 1250 kg sliperry hippo slides down a mud covered hill included at an angle at 18 degrees to the horizontal. a) if the coefficient of sliding friction between the hippo and the mud is .09, what force of friction impedes the hippo's motion down the hill? b) if the hill were steeper, how would this affect the coefficient of sliding friction?

for a i think im suppose to do (sin 18)(1250kg x 9.8m/s^2)(.09)= 347.64N but im not sure if im suppose to use cosine

for b i think htecoefficient of sliding friction would remain the same but im not 100%

can someone help?
