Answer:

The displacement and the distance were equal early in the run, however due to the shape of the track the distance is greater than the displacement.

The scalar reading during the process is 170. 5 Newton

<h3>How to determine the scalar reading</h3>

force = mass × acceleration

Given the mass = 55kg

In finding the acceleration, use the first equation of motion

v = u + at

u = 0

t = 2s

v = 6.5 m/s

Substitute the values

6.5 = 0 + 2a, make 'a' the subject

a = 6. 5÷ 2 = 3. 1 m/s²

Substitute the value of 'm' and 'a' in the original equation

F = 55× 3.1 = 170. 5 Newton

Hence, the scalar reading during the process is 170. 5 Newton

The winch takes in cable at the constant rate of 130 mm/s. if the cylinder mass is 115 kg, determine the tension in cable 1. neg
nikitadnepr [17]
By applying Newton's second law of motion;

ma = mg - T

Where,
m = mass; a = downward accelerations (+ve value) or upward acceleration (-ve value); g = gravitational acceleration; T = tension.

For the current case, the velocity is constant therefore,
a = 0

Then,
0 = mg - T
T = mg = 115*9.81 = 1128.15 N

Tension in the cable is 1128.15 N.

What is the primary ingredient of power yoga?
LuckyWell [14K]
The primary ingredient of power yoga was said to be heated. The heat makes the power yoga so particularly effective as a physical therapy. The heat is primarily used in shaping glasses to any figures that the person may want to. Power yoga can practically provide more space for fluids to carry the nutrients and remove toxins

A very light ideal spring having a spring constant (force constant) of 8.2 N/cm is used to lift a 2.2-kg tool with an upward acc
vampirchik [111]

Answer:

x = 3.5 cm

Explanation:

When spring is used as a lift tool

so the mass suspended on it will have spring force on it

So as per the force equation of mass we can say

F_{net} = ma

now net force on the mass is

F_{net} = kx - mg

F_{net} = kx - mg = ma

here we have

kx = mg + ma

now we have

x = \frac{mg + ma}{k}

x = \frac{2.2(9.8) + 2.2(3.25)}{8.2}

x = 3.5 cm
