A gull is flying horizontally 10.80 m above the ground at 6.00 m/s. The bird is carrying a clam in its beak and plans to crack t
UkoKoshka [18]

Answer:

v_y = 14.55 m/s

Explanation:

given,

height at which gull is flying = 10.80 m

speed of the gull = 6 m/s

acceleration due to gravity = 9.8 m/s²

Relative to the seagull, the x-speed is 0,

because the seagull has the same x-speed.

Only the y-speed counts:

v_y^2 = u^2 + 2 g h

v_y^2 = 0^2 + 2 g h

v_y = \sqrt{2gh}

v_y = \sqrt(2\times 9.8 \times 10.8)  

v_y = \sqrt(211.68)

v_y = 14.55 m/s

hence, the speed at which the clam smash the rock is v_y = 14.55 m/s

A jet airliner moving initially at 612 mph (with respect to the ground) to the east moves into a region where the wind is blowin
Ganezh [65]

Answer:

966.22 mph

Explanation:

Velocity of plane with respect to wind (Vp,w)= 612 mph east

velocity of wind with respect to ground, (Vw,g) = 362 mph at 15° North of

east

Write the velocities in vector form

V_{p,w}=612\widehat{i}

V_{w,g}=362\left ( Cos15\widehat{i}+Sin15\widehat{j} \right )= 349.67\widehat{i}+93.69\widehat{j}

Use the formula for the relative velocity

V_{p,w}=V_{p,g}-V_{w,g}

Where, V(p,w) is the velocity of plane with respect to wind

V(p,g) is the velocity of plane with respect to ground

V(w,g) is the velocity of wind with respect to ground

So, V_{p,g}=V_{p,w}+V_{w,g}

V_{p,g}=\left ( 612+349.67 \right )\widehat{i}+93.69\widehat{j}

V_{p,g}=961.67\widehat{i}+93.69\widehat{j}

Magnitude of velocity of lane with respect to ground

V_{p,g} = \sqrt{961.67^{2}+93.69^{2}}

V(p,g) = 966.22 mph

Derive a general formula for projectile motion with the object launched at an angle
vagabundo [1.1K]

Answer:

  y = x tan θ - (g / 2v₀² cos² θ) x²

Explanation:

An equation is called a general formula that relates the position on the x-axis and the height on the body's axis.

Let's write the position on each axis

X axis. No acceleration

         x = v₀ₓ t

Y Axis.  There is the acceleration of gravity

        y = v_{oy} t - ½ g t²

Let's clear the time in the first equation and substitute in the second

       y = v₀ sin θ  (x / v₀ₓ) - ½ g (x / v₀ₓ)²

       y = v₀ sin θ / v₀ cos θ x - ½ g x² / v₀² cos² θ

       y = x tan θ - (g / 2v₀² cos² θ) x²

This is the trajectory equation in projectile launching

A uniform meter stick is hung at its center from a thin wire. It is twisted and oscillates with a period of 5 s. The meter stick
rewona [7]

Answer:

The new time period is  T_2 =  3.8 \  s

Explanation:

From the question we are told that

  The period of oscillation is  T =  5 \ s

   The  new  length is  l_2  =  0.76  \ m

Let assume the original length was l_1 = 1 m

Generally the time period is mathematically represented as

         T  =  2 \pi   \sqrt{ \frac{ I }{ mgh } }

Now  I is the moment of inertia of the stick which is mathematically represented as

           I  =  \frac{m * l^2 }{12 }

So

        T  =  2 \pi   \sqrt{ \frac{  m * l^2 }{12 *   mgh } }

Looking at the above equation we see that

        T  \ \ \  \alpha  \ \ \  l

=>    \frac{ T_2 }{T_1}  =  \frac{l_2}{l_1}

=>    \frac{ T_2}{5} =  \frac{0.76}{1}

=>     T_2 =  3.8 \  s
