Write a balanced nuclear equation for the alpha decay of plutonium 244

A balanced nuclear equation for the alpha decay of plutonium 244 is as follows.

Explanation:

Alpha decay:

The nucleus emits an alpha particle containing two protons and two neutrons.

An alpha radioactive decay occurs when the nucleus has too many protons.

Plutonium  244 undergoes an alpha radioactive decay to form U- 240 isotope,

A balanced nuclear equation for the alpha decay of plutonium 244 is as follows.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

am i too late?
