Question

a bicycle increases its velocity from 10km /h to 15km/h in 6 seconds . calculate it's acceleration​

Answer 1

Answer:

Explanation:

we have the equation

v = u + at

u = 10× 5/18 = 25/9 m/s

v = 15× 5/18 = 25/6 m/s

t = 6 s

applying in equation,

25/6 = 25/9 + a×6

a×6 = 25/6 - 25/9

a×6 = 25/18

a= 25/ 18×6

a= 0.23 m/s²
