A driver of car was travelling at 54km-1.he suddenly applies the break on seeing a dog crossing his way and saved the dog.the car stops in 5sec 1.what

values did the driver display? 2.calculate the acceleration of the car? 3.plot the speed versus time graph of the car?
1. Values... you can do yourself
3. Meh


I think that is 54 kmph :p
So 54 kmph in mps = 54 *[5/18] --> I hope you know what is 5/18 , okay a hint : 5/18 = 1000/3600
So 54 *5/18=15 mps
So, U = 15mps
2. acceleration is v-u/t =0-15/5 = -3m/s^2
