Which has more kenetic energy: A 150 g bullet fired from a gun achieving a velocity of 440 m/s and a standard baseball weighing
aleksley [76]

Answer:

Bullet has more kinetic energy then baseball.

Explanation:

Mass of the bullet , m = 150 g = 0.150 kg

Velocity of the bullet = v = 440 m/s

Kinetic energy =\frac{1}{2}\times mass\times (velocity)^2

Kinetic energy of the bullet = K.E

K.E=\frac{1}{2}mv^2=\frac{1}{2}\times 0.150 kg\times (440 m/s)^2

=14,520 Joules

Mass of the baseball, m' = \frac{51}{4} oz= 0.36146 kg

(1 ounce = 0.0283495 kg)

Velocity of the baseball= v' = 105.1 mph

1 mile = 1609.34 m

1 hour = 3600 seconds

v'=\frac{ 105.1\times 1609.34 m}{3600 s}=46.98 m/s

Kinetic energy of the baseball = K.E'

K.E'=\frac{1}{2}m'v'^2=\frac{1}{2}\times 0.36146 kg\times (46.98 m/s)^2

=398.83 Joules

14,520 Joules > 398.83 Joules

K.E > K.E'

Bullet has more kinetic energy then baseball.

Testbank, Question 095 What is the expected major organic product from the treatment of 4-methyl-2-pentyne with excess hydrogen
Sedbober [7]

Answer:

See explanation and image attached

Explanation:

The addition of excess hydrogen to alkyne in the presence of a platinum catalyst leads to complete hydrogenation of the alkyne as shown in the image attached.

Therefore, an alkane is obtained as the major organic product when excess hydrogen reacts with an alkyne in the presence of a platinum catalyst.
