Answer: buzzer.

The working principle of a buzzer is the conversion of electrical energy to sound energy.

The switch just cuts or permits the flow of current, the motor convertes electrical or other kind of energy into mechanical energy, a bulb converts electrical energy into light and a battery converts chemical energy into electrical energy.

In the Olympic shot-put event, an athlete throws the shot with an initial speed of 12.0 m/s at a 40.0 ∘ angle from the horizonta
Gre4nikov [31]

Answer:

Explanation:

given,

initial speed of the shot = 12.0 m/s

angle = 40°

height at which shot leaves her hand = 1.80 m

v_x = 12 cos 40° = 9.19 m/s

v_y = 12 sin 40° = 7.71 m/s

time to reach maximum height =

     = \dfrac{v_y}{g}

     = \dfrac{7.71}{9.8}

     = 0.787 s

h = v_y t + \dfrac{1}{2}gt^2

h = 7.71 × 0.787 - 0.5 × 9.81 × 0.787²

h = 3.03 m

the maximum height attain = 3.03 + 1.8 = 4.83 m

now free fall from the maximum height

h =\dfrac{1}{2}gt^2

4.83 = \dfrac{1}{2}\times 9.8 \times t^2

t = 0.9928 s

total time = 0.9928 + 0.787 = 1.7798 s

range =

d = vₓ t

d = 16.36 m

vladimir1956 [14]

Answer:  x= 4.761 m/s

t=0.786 sec

Explanation: In a projectile motion (or 2D motion), the object is launched with an initial angle  and an initial velocity

The components of the velocity are

<em>The magnitude, which is the speed, and the direction in which the motion is happening.</em>

Similarly the displacement has the components

The last formula is valid only if the object is launched at ground level, as our frog does.  

There are two times where the value of y is zero, when t=0 (at launching time) and when it lands back from the air. We need to find that time t by making y=0

Dividing by t (assuming t different from zero)

Then we find the total flight as

Replacing this time in the formula of x

We can solve for

Knowing that x=2.20 m and °

We now compute t
