Question

Calculate the increase in the speed of the car in the term of km/h​

Answer 1

Answer:

Time taken to change speed for accelerated motion is obtained from the equation,

v = u + a t , where u and v are initial and final speeds respectively, a is acceleratioan and.

t is time taken to change the speed.

initial speed = 36 km/h = 36×(5/18) = 10 m/s.

final speed = 54 kmph = 54×(5/18) = 15 m/s.
