A10-n object moves at 1 m/s. its kinetic energy is
a) 10 j.
b) 0.5 j.
c) 1 j.
d) more than 10 j.

To solve this problem we will first find the Mass of the Object given by Newton's second law and then apply the Kinetic Energy Theorem.

According to Newton's second law we have to

Where,

F = Force

m = mass

a = Acceleration, at this case is the same gravitational acceleration ()

Therefore the mass of the object is

The cinematic energy theorem tells us that

Where,

m = mass

v = Velocity

Replacing

Therefore the correct answer is B.

answer: its c lololo
