A 11 547,83-N car is raised using a hydraulic lift, which

kati45 [8]

Answer:

75457.54816 N

Explanation:

$F_1$ = Initial force

$F_2$ = Weight of car = 11547.83 N

$r_1$ = Smaller radius = 5 cm

$r_2$ = Larger radius = 19.56 cm

From Pascal's law we have

$\dfrac{F_1}{A_1}=\dfrac{F_2}{A_2}\\\Rightarrow F_1=F_2\dfrac{A_1}{A_2}\\\Rightarrow F_1=11547.83\dfrac{\pi r_1^2}{\pi r_2^2}\\\Rightarrow F_1=11547.83\dfrac{5^2}{19.56^2}\\\Rightarrow F_1=754.57548\ N$

The force is 754.57548 N

You plan to throw stones by using a sling that you whirl over your head. You will whirl the stone in a horizontal circle with a

MariettaO [177]

Answer:

$330.635$ meter per second square

Explanation:

Given

Height ,h $= 2.50$ m

Radius, r $= 1.50$ m

Distance travelled, $d = 15.9$ m

Since, the stone is released and it falls towards the sky, its initial velocity is zero

As per equation

$h = ut + \frac{1}{2} gt^2\\$ , we will evaluate "t"

Substituting the given values in above equation, we get

$2.5 = 0 *t + 0.5 * 9.81 * t^2\\t^2 = \frac{2.5}{0.5*9.81}\\ t = \sqrt{0.5096} \\t = 0.714$

Velocity

$= \frac{d}{t} \\= \frac{15.9}{0.714}\\= 22.27$

centripetal acceleration

$= \frac{v^2}{r} \\= \frac{22.27^2}{1.5}\\ = 330.635\\$
