A ball is thrown downward from the top of a building with an initial speed of 25 m/s.

Bumek [7]

Answer:

h = 69.6 m

Explanation:

Data:

Vo = 25 m/s
t = 2.0 s
g = 9.8 m/s²
h = ?

Formula:

$\boxed{\bold{h=V_{0}*t+\frac{g*(t)^{2}}{2}}}$

Replace and solve:

$\boxed{\bold{h=25\frac{m}{s}*2.0\ s+\frac{9.8\frac{m}{s^{2}}*(2.0\ s)^{2}}{2}}}$

$\boxed{\bold{h=50\frac{m}{s^{2}}+\frac{9.8\frac{m}{s^{2}}*4\ s^{2}}{2}}}$

$\boxed{\bold{h=50\ m+\frac{39.2\ m}{2}}}$

$\boxed{\bold{h=50\ m+19.6\ m}}$

$\boxed{\boxed{\bold{h=69.6\ m}}}$

The building has a height of <u>69.6 meters.</u>

Greetings.

Francium decays with a half-life of 22 minutes. If we start out with 639 mg of francium,how much would remain after 2.7 hours?

Vinil7 [7]

Answer:

3.87 or 3.9 mg

Explanation:

2.7h * 60mins = 162mins

number of 1/2 lives = 162/22= 7.364

amount remaining = 639(1/2)^7.364 = 3.8796

answer = 3.87 or 3.9
