Problem 9:Consider a skier heading down a9.5 slope. Assume the coefficient of friction for waxed wood on wet snow is _k=0.10 and use a coordinate system in which down the slope is positive. Randomized Variables=9.5

Part (a) Calculate the acceleration of the skier in m/s². Numeric: A numeric value is expected and not an expression. a = __________________________________________ Part (b) Find the angle of the slope down which this skier could coast at a constant velocity in degrees. Numeric: A numeric value is expected and not an expression. = ______________________________

Problem 10:A74-kg fellow stands on a digital scale in an elevator that accelerates upwards from rest to3.5m/s in 2.00 s.

Calculate the scale reading, in newtons, during this process (The scale exerts an upward force on him equal to its reading.) Numeric: A numeric value is expected and not an expression. F = __________________________________________
