Answer:
Height = 53.361 m
Explanation:
There are two balloons being thrown down, one with initial speed (u1) = 0 and the other with initial speed (u2) = 43.12
From the given information we make the following summary
= 0m/s
= t
= 43.12m/s
= (t-2.2)s
The distance by the first balloon is
where
a = 9.8m/s2
Inputting the values
The distance traveled by the second balloon
Inputting the values
simplifying
Substituting D of the first balloon into the D of the second balloon and solving
Now we know the value of t. We input this into the equation of the first balloon the to get height of the apartment
Answer:
The speed of the plane relative to the ground is 300.79 km/h.
Explanation:
Given that,
Speed of wind = 75.0 km/hr
Speed of plane relative to the air = 310 km/hr
Suppose, determine the speed of the plane relative to the ground
We need to calculate the angle
Using formula of angle
Where, v'=speed of wind
v= speed of plane
Put the value into the formula
We need to calculate the resultant speed
Using formula of resultant speed
Put the value into the formula
Hence, The speed of the plane relative to the ground is 300.79 km/h.
Answer:
The work done on the gas is equal to the area under the curve pv diagram w = area of triangle = 1/2 (base)(height) = 1/2 (BC)(Ac) = 1/2 (3v - v)(3p - p) = 1/2 (9 vp - 3 vp - 3vp + vp) = 4 vp/2 W = 2 vp
