Question

A sports car accelerates from rest to 95 km/h in 4.3 s. What is its average acceleration in m/s2 ?

Answer 1

hey.
V1=0,. V2 =95*(5/18) m/s.
a= (V2-V1)/t.
a= 26.39 /4.3
a= 6.14 m/s^2.

Answer 2

Initial velocity(u) = 0m/s ( as the body is starting from rest )

Final velocity(v) = 95 km/hr = 95×1000/60×60 = 25 m/s

Time taken(t) = 4.3 seconds

Acceleration(a) = v-u/t = 25-0/4.3 = 5.81 m/s^2

Hope this helps...
