43.6m^3

Explanation:

The following were obtained from the question given:

V1 = 36.5m^3

P1 = 755mmHg

P2 = 632mmHg

V2=?

Using Boyle's law equation P1V1 = P2V2, the new volume can be obtain as follows:

P1V1 = P2V2

36.5 x 755 = 632 x V2

Divide both side by 632

V2 = (36.5 x 755)/632

V2 = 43.6m^3

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
