<h3><u>Answer</u>;</h3>

= 3.076 L

<h3><u>Explanation;</u></h3>

Using the Charles' Law;

V1/T1 =V2/T2

V1 =2.6 L, T1 = (-11 + 273) K =262 K

V2 = ? , T2 = (37 +273) k = 310 K

Therefore;

2.6/262 = V2/310

V2 = (2.6 × 310)/262

   <u> = 3.076 L </u>

Brut [27]
A) -0.5(9.8)*t^2 = -25(t-2) - 0.5(9.8)(t-2)^2 
-4.9t^2 = -25t + 50 - 4.9(t^2-4t+4) 
0 = -25t+50+19.6t - 19.6 
5.4t = 30.4 
t = 5.62962963 s 

b) h = -4.9(5.62962963)^2 
h = -155.2943759 
the building is 155.2943759 m high 

c) speed 0of first stone 
= at 
= 9.8*5.62962963 
= 55.17037037 m/s 
speed of second stone
= v + at
= 25+9.8*3.62962963 
= 60.57037037 m/s
