Problem:

Gabriel is driving a car along a high way with a velocity of 80Km/hr and increase its velocity at 90 km/hr. 0.5 hr. What is the acceleration of the car? following GRESA. pahelp po sa may alm niyan..

Given:

vi ( initial velocity ) = 80 km/hr ( 22.22 m/s )

vf ( final velocity ) = 90 km/hr ( 25 m/s )

t ( time ) = 0.5 hr ( 1800 s )

a ( acceleration ) = ? unknown

Solution:

We can solve the problem using the formula ( a = vf - vi / t )

a = vf - vi / t

   = 25 m/s - 22.22 m/s / 1800 s

   =  2.78 m/s / 1800 s

   = 0.0015 m/s²

Answer:

The acceleration is equal to 0.0015 m/s²
