A cynical block on an air table vibrates horizontally in SHM with an amplitude of 8.0cm and a frequency of 1.50Hz. If a smaller

AveGali [126]

Answer:

μ = 0.724

Explanation:

maximum acceleration for SHM

a = ω²A

ω = 2πf

a = 4π²f²A

a = 4π²(1.50)²(0.080) = 7.106... m/s²

μ = F/N = ma/mg = a/g = 7.106/9.81 = 0.7243...

I'm cynical that a block can be cynical. Wassa madder, doesn't trust anyone?

URGENT HELP !! The coefficients of static and kinetic frictions for plastic on wood are 0.53 and 0.40, respectively. How much ho

IRISSAK [1]

Answer:

43.83 N

Explanation:

Given that,

The mass of an object, m = 34.4 kg

The coefficients of static and kinetic frictions for plastic on wood are 0.53 and 0.40, respectively.

The force of static friction,

$F_s=\mu_smg\\\\F_s=0.53\times 34.4\times 9.8\\\\F_s=178.67\ N$

The force of kinetic friction,

$F_k=\mu_kmg\\\\F_k=0.40\times 34.4\times 9.8\\\\F_k=134.84\ N$

Net force acting on the object is :

F = 178.67-134.84

= 43.83 N

Hence, this is the required solution.
