Annie rides her snowboard down a hill sloped at 25 degrees. The coefficient of kinetic friction between her and her skies is .15. If her mass is 55 kg, hw fast is she excelerating? Assuming she starts from rest and the equation is v=v+a*t, what is her velocity after 7 seconds?

How do you solve for the acceleration at an incline?

I got that the acceleration is 5.6 meters per seconds sqaured because 308.7N/55kg.

Therefore, the final velocity is 39.2 meters per second.

IS THIS RIGHT?

Thanks all for your help!
