A pump is to lift 18 kg of water per minute tthrough a height of 3.6 m. what output rating (watts) should the pump have?

1 answer:

7 0

Given: Mass m = 18 Kg; Height h = 3.6 m; Time t = 60 s

Required: Power output in unit of Watts

Formula: P = mgh/t

P = (18 Kg)(9.8 m/s²)(3.6 m)/60 s

P = 10.58 J/s or Watts

An archer shoots a 150. gram arrow straight up in the air. (Do not try this at home.) The bow was drawn back 75.0 cm by a 175 N

Dmitry [639]

Answer:

The arrow rise 44.64 m high assuming air friction is negligible

Explanation:

According to the law of conservation of energy

Kinetic energy = Potential energy at highest

$\frac{1}{2}kx^2=mgh$ ----1

We know that F=kx

So, $k = \frac{F}{x}\\k=\frac{175}{0.75}$

Substitute the value in 1

$\frac{1}{2}(\frac{175}{0.75})(0.75)^2=0.15 \times 9.8 \times h\\\frac{\frac{1}{2}(\frac{175}{0.75})(0.75)^2}{0.15 \times 9.8}=h\\44.64 = h$

Hence the arrow rise 44.64 m high assuming air friction is negligible

If a car is taveling with a speed 6 and comes to a curve in a flat road with radius ???? 13.5 m, what is the minumum value the c

Lemur [1.5K]

Answer:

$\mu_s \geq 0.27$

Explanation:

The centripetal force acting on the car must be equal to mv²/R, where m is the mass of the car, v its speed and R the radius of the curve. Since the only force acting on the car that is in the direction of the center of the circle is the frictional force, we have by the Newton's Second Law:

$f_s=\frac{mv^{2}}{R}$

But we know that:

$f_s\leq \mu_s N$

And the normal force is given by the sum of the forces in the vertical direction:

$N-mg=0 \implies N=mg$

Finally, we have:

$f_s=\frac{mv^{2}}{R} \leq \mu_s mg\\\\\implies \mu_s\geq \frac{v^{2}}{gR} \\\\\mu_s\geq \frac{(6\frac{m}{s}) ^{2}}{(9.8\frac{m}{s^{2}})(13.5m) }\\\\\mu_s\geq0.27$
