Answer:
initial velocity=u=0m/s
Final velocity=v=56m/s
Distance=s=80m
Mass=m=13300kg
Force=F=?
Using second equation of kinematics
\boxed{\sf v^2-u^2=2as}
v

=2as
a denotes to acceleration
\begin{gathered}\\ \sf\longmapsto a=\dfrac{v^2-u^2}{2s}\end{gathered}
⟼a=

\begin{gathered}\\ \sf\longmapsto a=\dfrac{56^2-0^2}{2(80)}\end{gathered}
⟼a=

\begin{gathered}\\ \sf\longmapsto a=\dfrac{3136}{160}\end{gathered}
⟼a=

3136
\begin{gathered}\\ \sf\longmapsto a=19.6m/s^2\end{gathered}
⟼a=19.6m/s

According to Newtons second law
\boxed{\sf F=ma}
F=ma
\begin{gathered}\\ \sf\longmapsto Force=13300\times 19.6\end{gathered}
⟼Force=13300×19.6
\begin{gathered}\\ \sf\longmapsto Force=260680N\end{gathered}
⟼Force=260680N
Answer:
640
Step-by-step explanation:
if you want to get it firt
multiple 20×9=180
then multiply
40×9=360
total points of black coin =180
totak points of white coins=360and
total points of red coin=100
if we want total points in the carrom then add the total of all the coins
180+360+100=640
therforeo total points of carrm is 640
