The football ball $m=1kg$ was kicked up vertically with speed $v=30m/s$. Make the model of

movement track, also the graph of speed, knowing that $F_r=bv^2$ and $b=1 Ns^2/m^2$.

- The football ball $m=1 kg$ was kicked up vertically with speed $v=20 m/s$. Make the graph of speed and the y position.
- The stone was thrown horizontally with speed $v=10m/s$ from the building at height $h=15m$. Make the model of movement track, also the graph of speed.
- The mass $m=1 kg$ is moving on inclined plane, inclined with an angle $\theta=30$°. Kinetic friction coefficient $μ_k=0.2$. Make the graph of speed and the movement.
