Question

A car accelerates uniformly from 1km /h' to 36km /h' in 5s

Answer 1

Answer:

Hello Mate,

The answer is Acceleration(a) = 7 km/hr^2

Explanation:

Given,

Initial velocity(u) = 1 km/h

Final velocity(v) = 36 km/h

Time(t) = 5 seconds

Therefore, Aceeleration(a) = x

Using the first Equation of Motion, v = u  + at,

36 km/h = 1 km/h + 5x

36 - 1 km/h = 5x

35 km/h = 5x

Further Simlifying it, we get,

x = 35/5 = 7

Therefore, the acceleration obtained is 7 km/h^2

HOPE THIS HELPS YOU...
