I feel like i basically know how to do this question but I am not 100% sure
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 I am suppose to do (sin 18)(1250kg x 9.8m/s^2)(.09)= 347.64N but I am not sure if I am suppose to use cosine
for b i think htecoefficient of sliding friction would remain the same but I am not 100%
can someone help?
