A man stands on his balcony, 130 feet above the ground. He looks at the ground, with his sight line forming an angle of 70° with
jenyasd209 [6]

Answer:

d =  380 feet

Explanation:

Height of man = perpendicular= 130 feet

Angle of depression = ∅ = 70 °

distance to bus stop from man = hypotenuse = d = 130 sec∅

As sec ∅ = 1 / cos∅

so d = 130 sec∅    or d = 130 / cos∅

d = 130 / cos(70°)

d =  380 feet

A skateboarder jumps horizontally off the top of a staircase and lands at bottom of the stairs. The staircase has a horizontal l
e-lub [12.9K]

Answer:

The vertical velocity of the skater upon landing is 10.788 meters per second.

Explanation:

Skateboarder experiments a parabolic movement. As skateboarder jumps horizontally off the top of the staircase, it means that vertical component of initial velocity is zero and accelerates by gravity, the final vertical speed is calculated by the following expression:

v = v_{o} + g\cdot t

Where:

v_{o} - Initial vertical speed, measured in meters per second.

v - Final vertical speed, measured in meters per second.

g - Gravitational acceleration, measured in meters per square second.

t - Time, measured in seconds.

Given that v_{o} = 0\,\frac{m}{s}, g = -9.807\,\frac{m}{s^{2}} and t = 1.10\,s, the final velocity of the skater upon landing is:

v = 0\,\frac{m}{s} + \left(-9.807\,\frac{m}{s^{2}} \right)\cdot (1.10\,s)

v = -10.788\,\frac{m}{s}

The vertical velocity of the skater upon landing is 10.788 meters per second.

Jamal is at Six Flags playing at the arcade. At one booth he throws a 0.50 kg ball
Mekhanik [1.2K]

were solving for v velocity of the ball after it has hit the bottle. a. momentum ->p=mv->ball + bottle momentum during hit = ball + bottle momentum after hit-> ball (.5*21)+ bottle (.2*0) (it's 0 because the the bottle is standing still) = ball after hit (.5*v)+bottle after hit (.2*30) -> 10.5+0=.5v+6 ->4.5=.5v->v=9m/s

b. if bottle was heavier the ball would be slower so final velocity would decrease

[30 POINTS] An automobile steering wheel is shown. The ideal mechanical advantage of this wheel and axle = _____ .
mamaluj [8]

Rw/Ra = MA

18cm/2cm= MA

MA = 9

This means that Fi is 1/9 of the force applied to the axil. The distance travelled by Rw is 9 times more than Ri  is that you move 9 times more when turning the wheel using Rw.

Put more simply

Rw/Ra = Fa/Fw

  • Rw = Radius of the wheel
  • Ra = Radius of the axil
  • Fa = Force delivered on the axil
  • Fw = Force delivered by the wheel
