Answer:
86.4 m horizontal from landing spot
Explanation:
Find out how long before the ball hits the ground
vertical speed of ball = -2 m/s gravity = - 9.81 m/s^2
find time to hit ground from 100 m
( height will be<u> zero</u> when it hits the ground)
<u>0 </u>= 100 - 2 t - 1/2 ( 9.81) t^2
use Quadratic Formula to find t = 4.32 seconds
horizontal speed of ball = 20 m/s
in 4.32 seconds it will travel horizontally 20 m/s * 4.32 s = 86.4 m
Thermal energy is converted to radiative energy via molecular collisions and released as photons.

Answer:
a) 351351.35m/s
b) 1.044*10^{-8}kg/C
Explanation:
a) Electric force and magnetic force over the charge must have the same magnitude. From there we can compute the seep of the charge.
![F_E=F_B\\\\qE=qvB\\\\v=\frac{E}{B}=\frac{1.95*10^{5}V/m}{0.555T}=351351.35\frac{m}{s}](https://tex.z-dn.net/?f=F_E%3DF_B%5C%5C%5C%5CqE%3DqvB%5C%5C%5C%5Cv%3D%5Cfrac%7BE%7D%7BB%7D%3D%5Cfrac%7B1.95%2A10%5E%7B5%7DV%2Fm%7D%7B0.555T%7D%3D351351.35%5Cfrac%7Bm%7D%7Bs%7D)
b) the mass-charge ratio is given by:
![\frac{m}{q}=\frac{rB}{v}=\frac{(6.61*10^{-3}m)(0.555T)}{351351.35m/s}=1.044*10^{-8}\frac{kg}{C}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7Bq%7D%3D%5Cfrac%7BrB%7D%7Bv%7D%3D%5Cfrac%7B%286.61%2A10%5E%7B-3%7Dm%29%280.555T%29%7D%7B351351.35m%2Fs%7D%3D1.044%2A10%5E%7B-8%7D%5Cfrac%7Bkg%7D%7BC%7D)
