A soccer ball of mass 250 g is moving horizontally to the left with a speed $22 \mathrm{~ms}^{-1}$. This ball is kicked towards right with a velocity $30 \mathrm{~ms}^{-1}$ at an angle $53^{\circ}$ with the horizontal in upward direction. Assuming that it took 0.01 s for the collision to take place, the average force acting is $\left(\cos 53^{\circ}=\frac{3}{5}, \sin 53^{\circ}=\frac{4}{5}\right)$
