<span>B. a homogeneous mixture in which one substance is dissolved into another</span>
The velocity will remain unchanged (Newton’s 1st Law) unless a force acts on it. If no friction force, then the velocity remains constant.
Answer:
163.35
__________________________________________________________
<u>We are given:</u>
Mass of the object (m) = 36.3 kg
Velocity of the object (v) = 3 m/s
<u>Kinetic Energy of the object:</u>
We know that:
Kinetic Energy = 1/2(mv²)
KE = 1/2(36.3)(3)² [replacing the variables with the given values]
KE = 18.15 * 9
KE = 163.35 Joules
Hence, the cart has a Kinetic Energy of 163.35 Joules
Both of them are in big trouble ! I personally would write up each one of them for => no current valid driver's license, => no current vehicle insurance, => no current vehicle emission inspection sticker, => no visible current vehicle, => failure to signal turns, and => speeding in a school zone, since 19.4 m/s is equivalent to 43.4 mph.
