Problem

A projectile is launched from ground level and lands back at the same level. It travels

45\,\text{m}

horizontally and reaches a maximum height of

10\,\text{m}

above the launch point. Ignore air resistance and use

g=9.8\,\text{m/s}^2

. Which of the following is closest to the launch angle with respect to the horizontal? a)

48^{\circ}

42^{\circ}

25^{\circ}

60^{\circ}
