Answer:

v_f = 20 m / s

Explanation:

For this exercise let's use the relationship between momentum and moment

I = Δp

F t = m v_f - m v₀

as the body starts from rest v₀ = 0

F t = m v_f

v_f = $\frac{F t}{m}$

let's calculate

v_f = 4 2 / 0.4

v_f = 20 m / s

A textbook of mass 2.09 kg rests on a frictionless, horizontal surface. A cord attached to the book passes over a pulley whose d

Nutka1998 [239]

Answer:

The tension in the part of the cord attached to the textbook is 6.58 N.

Explanation:

Given that,

Mass of textbook = 2.09 kg

Diameter = 0.190 m

Mass of hanging book = 3.08 kg

Distance = 1.26 m

Time interval = 0.800 s

Suppose,we need to calculate the tension in the part of the cord attached to the textbook

We need to calculate the acceleration

Using equation of motion

$y=ut+\dfrac{1}{2}at^2$

$a=\dfrac{2y}{t^2}$

Put the value into the formula

$a=\dfrac{2\times1.26}{0.800}$

$a=3.15\ m/s^2$

We need to calculate the tension

When the book is moving with acceleration

Using formula of tension

$T=ma$

$T=2.09\times3.15$

$T=6.58\ N$

Hence, The tension in the part of the cord attached to the textbook is 6.58 N.

What is the mass of a student that weighs 3000N stands on one foot, balancing on a step stool.

Mkey [24]

Weight = (mass) x (gravity)

Mass = (weight) / (gravity)

Mass = (3000N) / (9.8 m/s^2)

Mass = 306.1 kg

But he could never stand on one foot balanced on a step stool. The poor kid weighs 675 pounds ! !
