Question

How far will a motorcycle that accelerates at 1.28 m/s2 travel as its velocity increases from 10.0 m/s to 20.0 m/s?

Answer 1

Answer: 117.1875 m

<<<<<<<<<<<< explanation >>>>>>>>>>>>>>>>>

v=u+at

here v = 20

u=10

a=1.28

so 20=10+1.28*t

==>t=10/1.28 seconds

also

s=ut+1/2 at²

s= 10*10/1.28 +1/2 *1.28 *10/1.28 *10/1.28 = 100/1.28+50/1.28=150/1.28=117.1875 m
