Question

A car is travelling at 54 km per hour if its velocity increases to 72 km per hour in 5 seconds then find the acceleration of the car in s i units

Answer 1

Hi friend
--------------
Your answer
--------------------

INITIAL VELOCITY = U = 54 km/h = 15 m/S

FINAL VELOCITY = V = 72 km/h = 20 m/s

TIME = T = 5 SECONDS

FINDING ACCELERATION (A)
------------------------------------------

V = U + AT. (FIRST EQ. OF MOTION)

20 = 10 + A*5
5A = 20 - 10
5A = 10
A = 10/5
A = 2 m/s²

THEREFORE,
--------------------

ACCELERATION = 2 m/s²
