here's the accurate answer
u=20 kmph =20 x 5/18 )m/s =50/9 m/s
v=50 kmph =( 50 x 5/18 )m/s =125/9 m/s
t=10 secondsa=?
as we know that:v=u+at
125/9 = 50/9 + a x 10125/9 - 50/9 = 10 a75/9 = 10 aa = 75/90a = 15/18a = 0.83 m/s^2
u=20 kmph =20 x 5/18 )m/s =50/9 m/s
v=50 kmph =( 50 x 5/18 )m/s =125/9 m/s
