Question

If a bicyclist, with an initial velocity of zero, steadily gained speed until reaching a final velocity of 13m/s, how far would she travel during this race? (Her time limit is 12s)

Answer 1

78 meters

Step-by-step explanation:

v=u+at

13=0+a×12

a=13/12 m/s^2

Now,

v²=u²+2as

13²=2×(13/12)×s

s=13×6=78 meters

Hope, this helps you.

Answer 2

156m

Step-by-step explanation:

• velocity=distance/time
• V=13, S=?, T=12s

13=S/12

• cross multiply

S= 13×12

S= 156m
