As per Newton's law we know that
F = ma
here we know that
F = 4 N
m = 2 kg
so from this equation we will have
4 = 2 a
a = 4/2 = 2 m/s^2
so the acceleration will be 2 m/s^2
The kinetic energy of a moving object is given by
where m is the object's mass and v its velocity.
In our problem, the initial kinetic energy is:
while the final kinetic energy is:
So, the kinetic energy lost by Lucy and her bike is
Explanation:
SI system is advantageous over mks system because SI system is intended to extend by its definition and has 7 base which is more than MKS system .
