Answer:
A frictional force acts on it
It has 50kg with a velocity of 1 m/s times the speed of the cart divided by 2 and multiplied by kinectic x plus 5
Your question seems incomplete, however, I might help you solve the problem even though the values are not given. The intensity of a traveling plane electromagnetic wave can be computed using the following equation:
S = (c/u0) * B^2
where s is the EM wave intesity
c is the speed of light
B is the magnetic field
u0 is the energy density
Answer:
Kinetic energy, form of energy that an object or a particle has by reason of its motion. ... Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.
