Question

a car is traveling along the road at 54 km/h it accelerates at 1m/s^2 a distance of 18m . how fast is it than traveling​

Answer 1

Answer:

16.2m/s

Explanation:

intial velocity (u) = 54km/h

convert km/h into m/s

5/18*54

= 15m/s

a = 1m/s^2

distance (s) = 18 m

v^2= u^2 +2as

v^2 = (15)^2 + 2* 1*18

= 225+ 36

= 261

v= √261

= 16.15 m/s

= 16.2 m/s
