Question

the speed of a cyclist increases from 2m per sec to 12m per sec in 50 sec. find acceleration

Answer 1

Hey! Here's your answer!

u = 2 m/s

v = 12 m/s

t = 50 s

a = (v - u)/t

  = (12 - 2)/50

  = 10/50

a = 0.2 m/s^2

Hope this helps! :)

Answer 2

v=u+at

12=2+a50

12-2=50a

10=50a

a=1/5
