✯♦intial velocity(U)= 10km/hr

= 10 × 5 / 18

= 2.77777

= 2.8 m/s

♦final velocity (V)= 15km /hr

=》 15 × 5 / 18

=》4.16 m/s(approx)

♦time (t ) = 6 sec

a =acceleration

 ✶ equation of motion ;

v = u + at

4.16 = 2.8 + 6a

6a + 2.8 = 4.16

6a = 4.16 - 2.8

6a = 1.36

a = 1.36 / 6

$a = 0.2 \: m/ {s}^{2}$

$hope \: it \: helps$
