Question

A bicycle increase its speed from 10 km/h to 15 km /h in 6 sec.calculate its acceleration

Answer 1

Hope this helps you!!

Answer 2

Hey here is your answer
_____________________

Initial speed of bicycle
= 10 km/hr = 10 × 5/18 = 50/18 m/s

Final speed of bicycle
= 15 km/hr = 15 × 5/18 = 75/18 m/s

Now ,

$acceleration \: = \frac{v - u}{t} \\ \\ a = \frac{ \frac{ 75}{18} - \frac{50}{18} }{6} \: m {s}^{ - 2} \\ \\ a = \frac{ \frac{25}{18}}{6} \: m {s}^{ - 2} \\ \\ a = \frac{25}{18 \times 6} \: m {s}^{ - 2} \\ \\ a = \frac{25}{108} \: m {s}^{ - 2} \\ \\ a = 0.2314814815 \: m {s}^{ - 2}$
