The driver is telling the truth, the radar gun must have been set incorrectly to record relative velocity.
The given parameters:
- <em>Speed of the driver observed by the stationary police officer, Vo = 44.7 m/s</em>
- <em>Speed of the driver, V = 26.8 m/s.</em>
- <em>Speed limit = 60 mph</em>
The speed limit of the driver in meter per second is calculated as follows;

From the speed limit, it is obvious that the driver's speed is within the limit. Thus, we can conclude that the driver is telling the truth, the radar gun must have been set incorrectly to record relative velocity.

i dont get it so much but
The weight of the bag pack is 8.2 N. g = 1.64 m/s2. Hence, the acceleration due to gravity on moon is 1.64 m/s2. sooo? is it right
Answer:43.311 J
Explanation:
Given
mass of frame
mass of wheel 
radius of wheel
v=3.22 m/s
Moment of inertia of each wheel\left ( I\right )=\frac{1}{2}mr^2[/tex]

kinetic Energy of whole cycle=Kinetic energy of wheels and frame+rotational energy of Wheels


K.E.=39.037+4.274=43.311J
