Object

A

moves along the

x

-axis with constant velocity

4\,\text{m/s}

starting from

x=0

. Object

B

is launched from the

y

-axis at

y=30\,\text{m}

aiming towards a point on the

x

-axis. If Object

B

is projected with speed

5\,\text{m/s}

, at what angle below the horizontal must it be projected to hit Object

A
