The radar device determines the vehicle's instantaneous speed.
I would argue that the purpose of the device is not to determine
whether individuals are driving safely. They only determine whether
individuals are driving within legal speed limits. There's much more
to 'safe' driving than that, but the radar gun can't detect it.
Answer:
For the purposes of your question, we can think of speed and velocity as being the same thing. Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four.

<span>D is the correct answer. If you wanted to know how fast a tiger can run, you would use meters and seconds. Meters will tell you the distance that the tiger ran and seconds will tell you how quickly the tiger ran the distance.</span>
Answer:
121km/h
Explanation:
Let speed of boat=xkm/h
Speed of water flow=33 km/h
Speed upstream=(x-33)km/h
Speed downstream=(x+33)km/h
Time=44 hrs
Time =77 hrs
We have to find the speed of boat.
Using the formula
Upstream distance=Downstream distance
Hence, the speed of boat=121km/h
