A man travels 25 kilometers in 15 minutes. A police officer stops him and writes a ticket for speeding. The posted speed limit is 80 kilometers per
hour. Did the man exceed the posted speed limit?

yes

Explanation:

cuz 15x2=30 30x2=60 60=1 hour, and the limited is 80 km per hour

15=25

15x4=60 25x4=100

so yes

he was going 100km per hour

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

force tends to be low and long diustance masses are high
