It was a children versus grown-ups competition at school. One event required the adult to throw a basketball as far as he could.

When it was the child's turn, he had to throw a baseball instead. The event coordinator said, "It's only fair!" Based on Newton's laws, was this event fair?

Answer:

Based on Newton's Law, the event is not fair because the ball which have large mass and have less acceleration will have less displacement if both the balls are thrown with same force.

Explanation:

Size of basketball is bigger than the size of baseball and the mass of basketball is greater than the mass of baseball.

We know from Newton's second law

F= m\times a

or

a=\frac{F}{m}

from above equation it is clear that ball with higher mass will have less acceleration if force is constant.

and if acceleration is less than according to Newtons second equation of motion, displacement of ball can be given as

s=ut+\frac{at^2}{2}

From above equation it is clear that the ball which have large mass and have less acceleration will have less displacement if both the balls are thrown with same force.

Two children hang by their hands from the same tree branch. the branch is straight, and grows out from the tree trunk at an angl
Ratling [72]

The net torque exerted by the children on the branch of the tree is 1382 N-m.

The torque exert by the kids is calculated as

T= 45.6*9.8*1.28*cos27.5°+36*9.8*(2.25-1.28)cos27.5°

T=1382 N-m

Hence, The net torque exerted by the children on the branch of the tree is 1382 N-m.

Calculate the pressure in bar of 2520 moles of hydrogen gas stored at 27 °c in the 180-l storage tank of a modern hydrogen-power
marin [14]

Answer: 347 bar


Explanation:

1) Data:


n = 2520 moles

T = 27 + 273.15 = 298.15 K

V = 180 liter

p = ?


2) Formula


Ideal gas equation: pV = nRT


3) Solution:


p = nRT/V = 2520 mol × 0.0821 atm×liter/K×mol ×298.15K / 180 liter = 342.7 atm


Conversion: 342.7 atm × 1,01325 bar / atm = 347 bar

A horizontal pole is attached to the side of a building. There is a pivot P at the wall and a chain is connected from the end of
PtichkaEL [24]

Answer:

Fscos63

Explanation:

Given that a horizontal pole is attached to the side of a building. There is a pivot P at the wall and a chain is connected from the end of the pole to a point higher up the wall. There is a tension force F in the chain. What is the moment of the force F about the pivot P?

Taking the moment from the pivot point P, that means the moment at point p = 0

Then, if we consider the weight mg of the pole, according to the principle of equilibrium : sum of the upward forces equal to the sum of the downward forces.

Therefore, mg = Fsinø ....... (1)

Also, taking moment at point P

Let the length of the pole = s

The length of the weight of the pole = 1/2 S

Fscosø = mgs/2

The distance s will cancel out

2Fcosø = mg ...... (3)

Substitute mg in equation 1 into equation 3

2fcosø = fsinø

F will cancel out

Tanø = 2

Ø = tan^-1(2)

Ø = 63.4 degree

The moment of force F about pivot point P will be

Moment = force × distance

Moment = Fcos63 × S

Moment = Fscos63
