Answer: The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving

Explanation:

a 4.60 kg mass is placed on top of a vertical spring, which compresses a distance of 2.31 cm. calculate the force constant (in n
Lerok [7]

The restoring force of the spring cancels the weight of the mass, so by Newton's second law

∑ F = F[spring] - mg = 0   ⇒   F[spring] ≈ 45.1 N

where m = 4.60 kg and g = 9.80 m/s². Then the spring constant is k such that by Hooke's law,

F[spring] = k x

where x = 0.0231 m. Then the spring constant is

k = F[spring]/x ≈ 1950 N/m

8. A 60 kg runner has 1500 J of kinetic energy. How fast is he moving?
tresset_1 [31]

Answer: 7.07 m/s

Explanation:

Mass of runner = 60 kg runner

Kinetic energy = 1500J

Speed of runner = ?

Recall that kinetic energy is the energy possessed by a moving object, and it depends on its mass and speed by which it moves.

Hence, K.E = 1/2 x mass x (speed)^2

1500J = 1/2 x 60kg x (speed)^2

1500J = 30kg x (speed)^2

(speed)^2 = 1500J/30kg

(speed)^2 = 50

To get the value of speed, find the square root of 50

speed = √50

speed = 7.07 m/s

Thus, the runner moves as fast as 7.07 m/s

Which would have the highest frequency of vibration? (Prove mathematically.) Pendulum A with a 200 g mass on a 1.0 m string Pend
Lera25 [3.4K]

Answer:

Pendulum B

Explanation:

The time period of a pendulum is given by :

T=2\pi\sqrt{\dfrac{L}{g}}

Case 1.

Mass, m = 200 g = 0.2 kg

Length of string, l = 1 m

Time, T_1=2\pi\sqrt{\dfrac{1\ m}{9.8\ m/s^2}}

T₁ = 2.007 Seconds

Since, f=\dfrac{1}{T_1}

f_1=\dfrac{1}{2.007}

f₁ = 0.49 Hz

Case 2.

Mass, m = 400 g = 0.4 kg

Length of string, l = 0.5 m

Time, T_2=2\pi\sqrt{\dfrac{0.5\ m}{9.8\ m/s^2}}

T₂ = 1.41 seconds

f₂=\dfrac{1}{T_2}

f₂=\dfrac{1}{1.41}

f₂ = 0.709 seconds

Hence, pendulum B have highest frequency of vibration.

As the mass of object increased it is density increased
Elan Coil [88]

Answer:

True.

Explanation:

The density of an object is given by its mass divided by its volume. It can be given as follows :

d=\dfrac{m}{V}

It can be seen that the density of an object is directly proportional to its mass. It means if the mass of an object increase, its density will also increase. Hence, the given statement is true.
