Answer 1

Answer:

A : 1M/S^2. IS THA CORRECT ANSWER.

Answer 2

Answer:

correct question

A car accelerates uniformly from 18kmh-1 to 36kmh-1 in 5 second.The acceleration is

given

intial velocity= 18 km/hr

final Velocity= 36km /hr

time = 5 minutes

to find

Acceleration

solution

▪️According to Newton's first law of motion :

$\fbox{v= u+ at}$

◾conversions

inital Velocity= 18 km/hr= 18 x 5/18= 5 m/sec

final Velocity= 36 km/hr= 10 m/sec

▪️put the values in the above formula-

▪️let the Acceleration of the car be 'a'

10= 5+ 5a

a= 5/5

a= 1 m/sec²
