Question

a bike travels with constant acceleration with a velocity of 20 m/s at the start of a 2 kilometer long track, and a velocity of 60 m/s by the end of the track. What is the constant acceleration of the bike?

Answer 1

Answer:

0.8 m/s^2

Step-by-step explanation:

formula

$v^{2} =u^{2} +2as\\\\60^{2} =20^{2} +2a*2000\\a=0.8$
