Answer:
a=v-u/t=2.22-1.66/10=0.56/10=0.056m/s²
Explanation:
60km/h=1.66m/s
80km/h=2.22m/s
Answer:
We have the equation : v=u+at
as we know,
v = final velocity
u = initial velocity
a = acceleration
t = time
Given:
Intial velocity = 80km/hr = 80×10/18 = 44.44 m/s
final velocity = 60km/hr = 60× 10/18 = 33.33 m/s
Acceleration= v-u/t
33.33-44.44
= ————————
10
-11.11
= ———
10
= 1.11
therefore ,acceleration is 1.11
