Question

A bus retards uniformly at the rate of 3m/s2 and stops in 10 sec.find the velocity?​

Answer 1

hope it helps

pls make as brainliest....

Answer 2

Answer:

Let acceleration of bus =-3m per s

Let acceleration of bus =-3m per sLet final velocity (v) =0

Let acceleration of bus =-3m per sLet final velocity (v) =0 Time taken =10 s

Let acceleration of bus =-3m per sLet final velocity (v) =0 Time taken =10 sUsing first equation of motion

Let acceleration of bus =-3m per sLet final velocity (v) =0 Time taken =10 sUsing first equation of motionV =U+AT

Let acceleration of bus =-3m per sLet final velocity (v) =0 Time taken =10 sUsing first equation of motionV =U+AT0=u +-3*10

Let acceleration of bus =-3m per sLet final velocity (v) =0 Time taken =10 sUsing first equation of motionV =U+AT0=u +-3*100=u-30

Let acceleration of bus =-3m per sLet final velocity (v) =0 Time taken =10 sUsing first equation of motionV =U+AT0=u +-3*100=u-30-u=-30

Let acceleration of bus =-3m per sLet final velocity (v) =0 Time taken =10 sUsing first equation of motionV =U+AT0=u +-3*100=u-30-u=-30u =30m per s
