Answer 2

Answer:

Explanation

acceleration is the rate of change of velocity of an object .si unit of acceleration is m/s^2.

first convert 108 km/hr to m/s

which is 108*5/18= 6*5=30m/s

hence the car acquires a speed of 30m/s in 30 s

by using first equation of motion

v=u +at

we get

30=0+30a

a=1m/s^2

hope this helpss!!
