A ball of mass 0.3 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below.
A ball of mass 0.3 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below.
The velocity of the ball as it leaves the kicker's foot is 17 m/s at angle of 47 ◦ above the horizontal. The top of the fence is 6 m high. The ball hits nothing while in flight and air resistance is negligible.
The acceleration due to gravity is 9.8 m/s2.
