Answer:
Global warming refers only to the Earth’s rising surface temperature, while climate change includes warming and the “side effects”
To solve this problem we will start from the definition of Force, as the product between the electric field and the proton charge. Once the force is found, it will be possible to apply Newton's second law, and find the proton acceleration, knowing its mass. Finally, through the linear motion kinematic equation we will find the speed of the proton.
PART A ) For the electrostatic force we have that is equal to
Here
q= Charge
E = Electric Force
PART B) Rearrange the expression F=ma for the acceleration
Here,
a = Acceleration
F = Force
m = Mass
Replacing,
PART C) Acceleration can be described as the speed change in an instant of time,
There is not 
then
Rearranging to find the velocity,
That depends on the wavelength of the electromagnetic radiation.
-- If the waves are long, then we use them for radio, TV, and cellphones.
-- If the waves are shorter than that, then we use them for GPS in the car.
-- If the waves are shorter than that, then we use them to heat meatloaf
in the microwave oven.
-- If the waves are shorter than that, then they warm us and they
make our plants grow ... like the ones we eat.
-- If the waves are shorter than that, then our eyes use them to see with.
-- If the waves are shorter than that, then they tan our skin.
-- If the waves are shorter than that, then they can cause cancer on
our skin.
-- If the waves are shorter than that, then they can cause cancer and
other diseases in places inside our body.
According to momentum conservation
15*3 = 45kgm/s
and the velocity of 5 kg mass will be
45/5 = 9 m/s
