Answer:

BC = 15.01

Step-by-step explanation:

Solve this question using a trigonometry ratio, which you can remember them all with SohCahToa, which says:

sinθ = opp / hyp

cosθ = adj / hyp

tanθ = opp / adj

θ means the "angle of reference" (angle we are talking about).

In this problem, θ is A = 65°,

To decide which trig. ratio to use, find out which sides we want to use. We will use AC = 7 because we know it.

We also use BC because we need to find it.

In relation to ∠A or θ, <u>AC is adjacent</u> and <u>BC is opposite</u>.

The ratio with adjacent and opposite is tangent.

tanθ = opp / adj Substitute the variables for this question

tanA = BC / AC Substitute the values you know

tan65° = BC / 7 Rearrange this and isolate C

BC = 7tan65° Multiply 7 and tan65 to find the missing side

BC = 15.011548...... Exact answer on your calculator

BC ≈ 15.01 Round to nearest hundredth

A brick is thrown upward from the top of a building at an angle of 250 above the horizontal, and with an initial speed of 15 m/s

mojhsa [17]

Answer:

(a) 25.08 m

(b) 2.05 m

Step-by-step explanation:

Let the height of the building be 'h'.

Given:

Angle of projection is, $\theta=25$ °

Initial speed is, $u=15\ m/s$

Time of flight is, $t=3.0\ s$

(a)

Consider the vertical motion of the brick.

Vertical component of initial velocity is given as:

$u_y=u\sin\theta\\\\u_y=15\sin(25)=6.34\ m/s$

Vertical displacement of the brick is equal to the height of the building.

So, vertical displacement = $-h$ (Negative sign implies downward motion)

Acceleration is due to gravity in the downward direction. So,

Acceleration is, $g=-9.8\ m/s^2$

Now, using the following equation of motion;

$-h=u_yt+\frac{1}{2}gt^2\\-h=6.34(3)-\frac{9.8}{2}(3)^2\\\\-h=19.02-44.1\\\\-h=-25.08\\\\h=25.08\ m$

Therefore, the building is 25.08 m tall.

(b)

Let the maximum height be 'H'.

At maximum height, the vertical component of velocity is 0 as the brick stops temporarily in the vertical direction.

So, $v_y=0\ m/s$

Now, using the following equation of motion, we have:

$v_y^2=u_y^2+2gH\\\\0=(6.34)^2-2\times 9.8\times H\\\\19.6H=40.2\\\\H=\frac{40.2}{19.6}=2.05\ m$

Therefore, the maximum height of the brick is 2.05 m.
