physics once again ...?

1. Consider the skier on a slope with an tilting angle of 65.2o. Her mass including equipment is 98.5 kg. What is her acceleration in unit of m/s2 if friction coefficient between her and the slope is 0.2 ? Please use g=10m/s2.

2. Block A is moving at v=2 m/s on the leveled ground. The mass of block A is 45.8 kg. The coefficient of friction is 0.41. What is the friction on block A? Use g=10 m/s2.

Update:

thanks
