Wendy rode her bicycle 87 meters in 12 seconds what is her speed? a- 0.14m/s
b-0.8m/s
c-7.3m/s
d-9.5m/s

A

Explanation:

Speed = Distance /  time

Speed = 87 meters / 12 seconds

Speed = 7.25 m/s

Round to 7.3 m/s

c. 7.3 m/s

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
