Question

The motorcycle specifications are given below. Find the time and distance required to decelerate from 100 kmph to a standstill at a deceleration of 10 m/s 2 . Also, find the effort required to pull the lever and comment whether it is within ergonomic limits for an average human being. Assume that the rider applied the front brakes only. Find out rise in temperature of the front Disc. (Ignore Heat dissipation due to convection and radiation

Answer 1

Answer:

25/9 sec

38.58 m

Step-by-step explanation:

Find the time and distance required to decelerate from 100 kmph to a standstill at a deceleration of 10 m/s 2

Speed = 100 km/hr

= 100 * 1000 / 3600 m/s

= 250/9 m/s

v = u + at

a = - 10m/s²  

v = 0 standstill

0 = 250/9 - 10t

=> t = 25/9 sec

v² - u² = 2as

=> 0 - (250/9)² = 2(-10)S

=> S = 3125/81

=> S = 38.58 m
