What provides the force on the person in the passenger seat?

1 answer:

6 0

The forces that make a passenger speed up, slow down, or
turn a curve are the same forces that have the same effect
on the driver and anybody else in the car.

-- Speeding up . . .

the back of the seat
    friction between the car seat and the seat of your pants

-- Slowing down . . .

the seat belt
      friction between the car seat and the seat of your pants

-- Turning away from a straight line . . .

      the seat belt
friction between the car seat and the seat of your pants
the door, or whatever or whomever you're leaning against

In addition to their remarkable top speeds of almost 60 mph, cheetahs have impressive cornering abilities. In one study, the max

Sav [38]

Answer:

the minimum value of the coefficient of static friction between the ground and the cheetah's feet is 1.94

Explanation:

Given that ;

the top speed of Cheetahs is almost 60 mph

In cornering abilities ; the maximum centripetal acceleration of a cheetah was measured to be = 19 m/s^2

The objective of this question is to determine the what minimum value of the coefficient of static friction between the ground and the cheetah's feet is necessary to provide this acceleration?

From the knowledge of Newton's Law;

we knew that ;

Force F = mass m × acceleration a

Also;

The net force $F_{net}$ = frictional force $\mu_k mg$

so we can say that;

m×a = $\mu_k mg$

where;

the coefficient of static friction $\mu_k$ is:

$\mu_k = \dfrac{m*a}{m*g}$

$\mu_k = \dfrac{a}{g}$

$\mu_k = \dfrac{19 \ m/s^2}{9.81 \ m/s^2}$

$\mathbf{\mu_k}$ = 1.94

Hence; the minimum value of the coefficient of static friction between the ground and the cheetah's feet is 1.94

Help ASAP please (: The waves with the MOST energy have

tino4ka555 [31]

Answer: C

high; large

Explanation:

The wave energy is related to its amplitude and frequency.

The wave energy is proportional to the amplitude of the wave. So, wave with the most energy will have high amplitude.

Also, frequency is related to wave energy. The larger the frequency, the more the energy of the wave.

Therefore, The waves with the MOST energy have high amplitudes and large

frequencies.

serious [3.7K]

Answer:

The answer to your question is:

a) t = 3.81 s

b) vf = 37.4 m/s

Explanation:

Data

height = 71.3 m = 234 feet

t = 0 m/s

vf = ?

vo = 0 m/s

Formula

h = vot + 1/2gt²

vf = vo + gt

Process

h = vot + 1/2gt²

71.3 = 0t + 1/2(9.81)t²

2(71.3) = 9,81t²

t² = 2(71.3)/9.81

t² = 14.53

t = 3.81 s

vf = 0 + (9.81)(3.81)

vf = 37.4 m/s
