Problem

A truck of height

4\,\text{m}

is moving away from a cannon with a constant speed of

10\,\text{m/s}

and is accelerating with

1\,\text{m/s}^{2}

. When the truck is

40\,\text{m}

away, a shell is fired at an angle of

45^{\circ}

with a speed of

40\,\text{m/s}

. Determine if the shell hits the top of the truck, or lands in front or behind it. Take

g = 10\,\text{m/s}^{2}
