Question

starting from a stationary position, Rahul paddles his bicycle to attain a velocity of 6m/s in 30 s.then the applies brakes such that the velocity of the bicycles comes down to 4m/s in the next 5 s. calculate the acceleratiothe on of the bicycle in both cases. plz someone give me its ans step by step fast............it's urgent

Answer 1

Answer:

Here is your answer!!

Formula for acceleration= v-u/t

Answer 2

Answer:

u = 0

v= 6m/s

a = v-u/t

  = 6-0/30

  = 6/30

  = 1/5 = 0.2 m/s2

second case,

u=6 m/s

v= 4m/s

a= v-u/t

  =4-6/5

   = -2/5  =  - 0.4 m/s2

hope it helps :)
