Answer:
- a = 0.22 m /s²
Explanation:
Initial velocity = u = 10 km /hr
= 10 x 5 /18
= 2.77777
= 2.8 m /s
Final velocity = v = 15 km / hr
= 15 x 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 = 0.22 m /s²
