Solved Problems in Kinematics---2
P.1. P.2. P.3. On an open ground a motorist follows a track that turns to his left by an angle of 60 degree after every 500 m. Starting from a given turn, specify the displacement of the motorist at the third, sixth and eighth run. Compare the magnitude of displacement with the total path length covered by the motorist in each case. P.4. A drunkard walking in a narrow lane takes 5 steps forward and 3 steps backward, followed again by 5 steps forward and 3 steps backward, and so on. Each step is 1 m long and requires 1 s. plot the x-t graph of his motion. Determine graphically or otherwise how long the drunkard takes to fall in a pit 9 m away from the start. P.5. A man walks on a straight road from his home to a market 2.5 km away with a speed of 5 km/h. On reaching the market be instantly turns and walks back with a speed of 7.5 km/what is the (a) magnitude of average velocity and (b) average speed of the man, over the int...
