$P=\frac{dW}{dt}=\frac{d}{dt}(Fr)=F\frac{dr}{dt}=Fv$

$P=Fv$
$P=(10.0N)(0.5\frac{m}{s})$
$P=\frac{5N-m}{s}$
$P=\frac{5J}{s}$
$P=5W$

Answer:

The tennis ball is moving 6m/s.

Explanation:

displacement(s) = 0.5 m

intial velocity(u) = 4 m/s

acceleration(a) = 10 m/s²

As we know,

2as = v²-u²

or, 2 ×10 × 0.5 = v²-4²

or, 10 = v²-16

so, v² = 36

so, v (final velocity) = 6 m/s
