E-p22mp-x221A-2mE

Stationary nucleus $^{238} U$ decays by a emission generating a total kinetic energy T:
$_{92}^{238} U \to_{90}^{234} T h +_{2}^{4} α$
What is the kinetic energy of the $α - p a r t i c l e$ ?
Slightly less than $T / 2$
$T / 2$
Slightly less than $T$
Slightly greater than $T$

$E = \frac{p^{2}}{2 m}$
$p = \sqrt{2 m E}$
