Kai was 200 meters north of the library when he remembered he had to return some books to the library. it took him 200 seconds t
o do the round trip. which best describes kai's roundtrip? his speed was 1 m/s, and his velocity was 0. his speed was 2 m/s, and his velocity was 0. his speed was 1 m/s, and his velocity was 1 m/s north. his speed was 2 m/s, and his velocity was 2 m/s south.

Answer: The correct option is 'his speed was 2 m/s, and his velocity was 0.'
Explanation:
In a Round trip the stating point and finishing point are the same.
The distance covered by Kai in 200 seconds = AB+BA =
200 m+200 m = 400 m
Speed of the kai =
Displacement = shortest path covered = AB - BA = 200 m - 200 m =0 m
Velocity of the kai =
Hence, the correct option is 'his speed was 2 m/s, and his velocity was 0.'

Answer:
K.E = 4800 Joules.
Explanation:
Given the following data;
Mass = 600 kg
Velocity = 4 m/s
To find the kinetic energy;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
K.E = 4800 Joules.
