Question

U=20kmph V=50 m/s t= 2seconds S=200cm A=?​

Answer 1

Explanation:

s=ut+at²

200=40+2a

200-40=2a

160/2=a

Therefore, a=80

Please mark it as the brainliest answer

Answer 2

Answer:

22.22 m/s²

Explanation:

u = 20km/h  =  (20 x 1000)/3600 = 50/9m/s

v = 50m/s

t = 2s

a = ?

a = (v - u) / t

=>  (50 - 50/9) / 2

(400/9)/2

= 200/9

= 22.22 m/s²
