Cars driving 15.7 m/s on a flat ground drives off of 25.3 m High cliff how far from the base of the cliff does it land

MA_775_DIABLO [31]

The car lands 35.6 m from the base of the cliff

Explanation:

The motion of the car is a projectile motion, which consists of two independent motions:

- A uniform motion (constant velocity) along the horizontal direction

- A uniformly accelerated motion, with constant acceleration (acceleration of gravity) in the downward direction

We start by analyzing the vertical motion, in order to find the time of flight of the car. We do it by using the following suvat equation:

$s=u_y t+\frac{1}{2}at^2$

where:

s = 25.3 m is the vertical displacement of the car (the height of the cliff)

$u_y=0$ is the initial vertical velocity of the car (because it is moving horizontally)

t is the time of the fall

$a=g=9.8 m/s^2$ is the acceleration of gravity

Solving for t, we find :

$t=\sqrt{\frac{2s}{g}}=\sqrt{\frac{2(25.3)}{9.8}}=2.27 s$

Now we can analyze the horizontal motion of the car, which moves with constant horizontal velocity of

$v_x = 15.7 m/s$

Therefore, the horizontal distance covered in a time t is

$d=v_x t$

and by substituting t = 2.27 s, we find the how far from the base of the cliff the car lands:

$d=(15.7)(2.27)=35.6 m$

A laser emits light at power 6.20 mW and wavelength 633 nm. The laser beam is focused (narrowed) until its diameter matches the

Ipatiy [6.2K]

Answer:

a) S = 1.69 10⁹ W/m², b) P = 5.63 Pa , c) F = 20.6 10⁻¹² N

Explanation:

a) The intensity defined as the energy per unit area

S = U / A

Area of a circle is

W = 6.2 mw = 6.2 10-3 W

R = 1080 nm = 1080 10⁻⁹ m = 1.080 10⁻⁶ m

A = π R2

A = π (1,080 10⁻⁶)²

A = 3.66 10 -12 m²

S = 6.2 10-3 / 3.66 10-12

S = 1.69 10⁹ W / m²

b) The radiation pressure

P = 1 / c (dU / dt) / A

S = (dU / dt) / A

P = S / c

P = 1.69 10 9 / 3. 108

P = 5.63 Pa

c) the definition of pressure is force over area

P = F / A

F = P A

F = 5.63 3.66 10⁻¹²

F = 20.6 10⁻¹² N

d) for this we use Newton's second law

F = ma

a = F / m

skad [1K]

Explanation:

Not being able to see the picture attached and supposing the ground level is considered to be the water level so to be able to find out the velocity you need to score into the hoop you need to use the combined force ( resulting force) to throw the ball at 6.50 m distance, 1 m below to where you are standing
