Answer to Question #85463 in Mechanics | Relativity for Akoma Daniel

Question

A man standing on the ground wants to climb to the top of a vertical pole 13meters tall.He climbs 5meters in 1second and then slips downwards 3meters in the next second.He gains climb 5meters in 1 second and slip by 3meters in the next second,and so on.Draw the x-1 graph of the motion of the man and hence find the time it will take the man to reach the top of the pole

Answer 1

The man climbs 5 m in one second and slips downwards 3 m in the next second. So the man is effectively climbing 2m in 2 seconds. After 8 seconds of climbing and slipping, the man would reach a height of 8 m. On the 9th second the man will climb the remaining 5m.

Answer: 9 s.
