Amass m slides upward along a rough plane surface inclined at angle θ= 0.21 in radians to the horizontal. initially the mass has a speed vo = 2.13 m/s, before it slides a distance l = 1.0 m up the incline. after sliding this distance the new speed of the mass isvo/ 3 measured in m/s. what is the acceleration of the sliding mass?
