How does Newton's second law of motion can be used to calculate the acceleration of an object?

1 answer:

4 0

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Use the Law of Cosines, where you have a triangle with included angle of 145 degrees and sides of 16 and 18. You are then solving the equation: 

d^2 = 16^2 + 18^2 - 2(16)(18)cos(145)

When you drink cold water, your body must expend metabolic energy in order to maintain normal body temperature (37Â° C) by warmi

Gelneren [198K]

Answer:

7.72 Liters

Explanation:

normal body temperature = T_body =37° C

temperature of ice water = T_ice =0°c

specfic heat of water = c_{water} =4186J/kg.°C

if the person drink 1 liter of cold water mass of water is = m = 1.0kg

heat lost by body is Qwater =mc_{water} ΔT

= mc{water} ( T_ice - T_body)

= 1.0×4186× (0 -37)

= -154.882 ×10^3 J

here negative sign indicates the energy lost by body in metabolic process energy expended due to brisk - hour long walk is Q_{walk} = 286 kilocalories

= 286×4186J

so number of liters of ice water have to drink is

n×Q_{water} =Q_{walk} n= Q_{walk}/ Q_{water}

= 286×4186J/154.882×10^3 J

= 7.72 Liters

Answer:

9000RPM

Explanation:

"Angular velocity" is directly related to kinetic energy, that is, the Kinetic energy equation would allow an approximation to the resolution investigated in the problem.

The equation for KE is given by:

$KE = \frac{1}{2} lw ^ 2$

Now, starting from there towards the Angular equation of kinetic energy, the moment of inertia (i) is used instead of mass (m), and angular velocity (w) instead of linear velocity (V)

That's how we get

$KE_{Angular} = \frac{1}{2} Iw^2$
