Respuesta :
The mass m₂ for the unknown mass numerically, in grams, to two significant digits is 0.5 kg.
How is the mass calculated ?
Let us assume that,
mass m1 = 0.500 kg ,
an angle = 30.0 °
fμ = 0.400
a = 0.500 m/s²
The equation for the Newton's second law is given as
∴ m₁ × g - T = m₁ × a
where,
∴ T = m₁ × (g - a)
∴ T = 0·5 × (9·8 - 0·5)
∴ T= 4·65 N
Therefore for
∴ T - uN - m₂ × g × sinθ = m₂ × a
∴ 4·65 = m2 × 8·8
∴ m2 = 0·52 kg
Hence the unknown mass is 0.5 kg
What is mass ?
- Mass is an intrinsic feature of a body.
- Mass is a standard mechanical quantity.
- Until the discovery of the atom and particle physics, it was thought to be tied to the amount of matter in a physical body.
- The amount of matter in a body is defined as its mass.
- The kilogram is the SI unit of mass (kg).
- The mass formula is as follows: Mass = Density × Volume
- It's worth noting that a body's mass is constant, it never changes.
- Only in extreme instances, when a large amount of energy is provided or taken from a body, can the mass be affected.
