Q1. A car can decelerate at -3.40m/s2 without skidding while coming to rest on the level road. What would be the magnitude of its deceleration if the road were inclined at 14° uphill? Suppose the same static friction coefficient.

Q2. A uniform plank of length 5.8m and weight 229N rests horizontally on two supports, with 1.10 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 450N walk on the overhanging part of the plank before it just begins to tip?
