Answer:

The mechanical advantage is 1.

Explanation:

Given;

input force, F₁ = 10 N

output force, F₀ = 10 N

mechanical advantage is called force ratio and it is given as;

M.A = output force / input force

M.A = 10 N / 10 N

M.A = 1

This is an ideal machine scenario.

Therefore, the mechanical advantage is 1.

A car is traveling at an average speed of 70 m/s. How many km would the car travel in 6.5 hrs. ?
docker41 [41]

Answer:

<h2>38,769.23 miles</h2>

Explanation:

given:

A car is traveling at an average speed of 70 m/s.

find:

How many km would the car travel in 6.5 hrs. ?

solution:

distance = velocity over time

let velocity = 70 m/s

           time = 6.5 hrs.

convert velocity 70 m/s into m/h for consistency of units.

<u>70 mi. </u> x   <u>3600 sec.</u>  =  252,000 mi/hour

  sec.          1 hr.

now plugin values into the formula d = v/t

d = <u>252,000 miles/hour </u>

              6.5 hours

d = 38,769.23 miles

therefore, the distance travelled in 6.5 hours with a speed of 70 m/s is 38,769.23 miles

Apilot of mass 70 kg rides a fighter jet The fighter jet moves in a vertical circle of radius 100 m at a constant
Cerrena [4.2K]

Answer:

the  force exerted by the seat on the pilot is 10766.7 N

Explanation:

The computation of the force exerted by the seat on the pilot is as follows:

F = Mg + \frac{MV^2}{R}\\\\= 70 \times 9.81  + \frac{70 \times 120^2}{100}\\\\= 10766.7 N

Hence, the  force exerted by the seat on the pilot is 10766.7 N

A hockey stick of mass ms and length L is at rest on the ice (which is assumed to be frictionless). A puck with mass mp hits the
krek1111 [17]

Answer:

L = mp*v₀*(ms*D) / (ms + mp)

Explanation:

Given info

ms = mass of the hockey stick

uis = 0 (initial speed of the hockey stick before the collision)

xis = D (initial position of center of mass of the hockey stick before the collision)

mp = mass of the puck

uip = v₀ (initial speed of the puck before the collision)

xip = 0 (initial position of center of mass of the puck before the collision)

If we apply

Ycm = (ms*xis + mp*xip) / (ms + mp)

⇒  Ycm = (ms*D + mp*0) / (ms + mp)

⇒  Ycm = (ms*D) / (ms + mp)

Now, we can apply the equation

L = m*v*R

where m = mp

v = v₀

R = Ycm

then we have

L = mp*v₀*(ms*D) / (ms + mp)
