You are investigating how objects move when they are dropped from different heights. To collect your data, you drop a 1 kg weigh
ASHA 777 [7]

The time of motion of the 5 kg object will be the same as 1 kg since both objects are dropped from the same height.

The given parameters;

<em>Mass of the first object, m1 = 1 kg</em>

<em>Mass of the second object, m2 = 5 kg</em>

The final velocity of the objects during the downward motion is calculated as follows;

v_f = v_0 + gt\\\\v_f = 0 + gt\\\\\v_f = gt

The time of motion of the object from the given height is calculated as;

h = v_0 t + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\gt^2 = 2h\\\\t^2 = \frac{2h}{g} \\\\t = \sqrt{\frac{2h}{g} }

The time of motion of each object is independent of mass of the object.

Thus, the time of motion of the 5 kg object will be the same as 1 kg since both objects are dropped from the same height.

As the earth rotates, what is the speed of a physics student in Miami, Florida, at latitude 26∘? Ignore the revolution of the ea
ASHA 777 [7]

Answer:

v =418 m/s

Explanation:

given,

Radius of earth = 6400 Km

speed of a physics student in Miami, Florida, at latitude 26° = v

time period of rotation = 24 hour = 24 × 3600

                                                       = 86400 s

distance = speed × time

v = \dfrac{distance}{time}

v = \dfrac{6400\times cos (26^0)\times 2 \pi }{86400}

v =0.41831 Km/s

v =418 m/s

hence, the velocity of the student is equal tov =418 m/s

An object of mass 300 kg is observed to accelerate at the rate of 4 m/s 2 . Calculate the force required to produce this acceler
Marianna [84]

Answer:

F = 1200 N

General Formulas and Concepts:

<u>Forces</u>

Newton's Second Law of Motion: F = ma

  • F is force (in N)
  • m is mass (in kg)
  • a is acceleration (in m/s²)

Explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>m</em> = 300 kg

<em>a</em> = 4 m/s²

<u>Step 2: Find Force</u>

  1. Substitute in variables [Newton's Second Law of Motion]:                           F = (300 kg)(4 m/s²)
  2. Multiply:                                                                                                            F = 1200 N
