Answer:

3000 m/s

Explanation:

The kinetic energy is:

KE = 3/2 kT

where k is Boltzmann constant and T is absolute temperature.

Kinetic energy is also:

KE = 1/2 mv²

where m is the mass and v is the speed.

1/2 mv² = 3/2 kT

mv² = 3kT

v = √(3kT / m)

v = √(3 × 1.38×10⁻²³ J/K × (273 + 27) K / 1.38×10⁻²⁷ kg)

v = 3000 m/s

evablogger [386]

Answer:

The soda is being sucket out at a rate of 3.14 cubic inches/second.

Explanation:

R= 2in

S= π*R²= 12.56 inch²

rate= 0.25 in/sec

rate of soda sucked out= rate* S

rate of soda sucked out=  3.14 inch³/sec

A batter hits a 0.140-kg baseball that was approaching him at 19.5 m/s and, as a result, the ball leaves the bat at 44.8 m/s in
Arada [10]

Answer:

5295.3 N

Explanation:

According to law of momentum conservation, the change in momentum of the ball shall be from the momentum generated by the batter force

mv + P = mV

P = mV - mv = m(V - v)

Since the velocity of the ball before and after is in opposite direction, one of them is negative

P = 0.14(44.8 - (-19.5)) = 9 kg m/s

Hence the force exerted to generate such momentum within 1.7ms (0.0017s) is

F = P/t = 9/0.0017 = 5295.3 N
