a car acquires a speed of 40km/hour in 30secs in just after the start what is the acceleration of the car

Question

acceleration

Answer 1

a = (delta v) / t

 

delta v = 40 km/hour

 

t = 30 sec = (30 / 360) hours = 0.08333 hours

 

a = (delta v) / t = (40 km/hour) / (0.08333 hours) = 480.02 km/hour^2
