a car travelling at 36 kilometre per second speed up to 72 km per second five second what is its us relation if the same caste of in 22nd what is it's acceleration
Answers
Final velocity v=72 km/h=72*1000/3600=20 m/s.
v=u+at
a=(v-u)/t=(20–10)/5=2 m/s^2
So acceleration = 2 m/s^2
Case II:
Initial velocity u =72 km/h= 20 m/s
Final velocity v= 0 m/s
a=(v-u)/t=(0–20)/20=-1 m/s^2
acceleration= -1 m/s^2
retardation/deceleration= +1 m/s^2
