A boy drops a 0.10 kg stone down a 150 m well and listens for the echo. The air temperature is 20°C. How long after the stone is

S_A_V [24]

Use formula for Echo which is Velocity=2(Distance)/time so 343=2(150)/T 343T=300..T=300/343=0.9 seconds

Answer:

22) 5.6 Kg.m/s

23) 0.067 Kg

24) 1.16 m/s

Explanation:

Momentum is found by multiplying mass and velocity

P=mv where P is momentum, m is mass of object and v is the velocity

Given

Mass, m=2 Kg

Rate, v=2.8 m/s

Relationship

P=mv

Solution

P=mv=2*2.8=5.6 Kg.m/s

Given

Momentum, p=0.1 Kg.m/s

Rate, v=1.5 m/s

Relationship

P=mv and making m the subject then

$m=\frac {P}{v}$

Solution

$m=\frac {0.1 Kgm.s}{1.5 m/s}\approx 0.067 Kg$

Given

Momentum, $p=4.9\times 10^{8} Kg.m/s$

Mass, $m=4.23\times10^{8} Kg$

Relationship

P=mv and making v the subject then

$v=\frac {P}{m}$

Solution

$m=\frac {4.9\times 10^{8} Kgm.s}{4.23\times10^{8} }\approx 1.16 m/s$
