1.	A bicycle increase its velocity from 10km/h to 15km/h in 6sec . Calculate its acceleratetion?
Answer» Initial velocity = u = 10 km /hr= 10 x 5 /18= 2.77777= 2.8 m /sFinal velocity = v = 15 km / hr= 15 x 5 / 18= 4.16 m /s [ approx .]Time = t = 6 seca = accelerationEquation of motion :v = u + at4.16 = 2.8 + 6a6a + 2.8 = 4.166a = 4.16 - 2.86a = 1.36a = 1.36 / 6a = 0.22 m /s²
