5 0

Answer:

2π/[28 x (10^-3)]

Explanation:

Angular speed : ω=2π/T

T = 28ms = 28 x (10^-3) s

Angular speed = 2π/[28 x (10^-3)]

17. A 25 kg block is initially at rest on a rough, horizontal surface. A horizontal force of 75 N is required to set
lapo4ka [179]

Answer:

0.30581

0.24464

Explanation:

\mu_s = Coefficient of static friction

\mu_k = Coefficient of kinetic friction

F_f = 75 N

F_k = 60 N

Normal force

F_n=mg\\\Rightarrow F_n=25\times 9.81\\\Rightarrow F_n=245.25\ N

Frictional force

F_f=\mu_sF_n\\\Rightarrow \mu_s=\frac{F_f}{F_n}\\\Rightarrow \mu_s=\frac{75}{245.25}\\\Rightarrow \mu_s=0.30581

The coefficient of static friction is 0.30581

Kinetic force

F_k=\mu_kF_n\\\Rightarrow \mu_k=\frac{F_k}{F_n}\\\Rightarrow \mu_s=\frac{60}{245.25}\\\Rightarrow \mu_s=0.24464

The coefficient of kinetic friction is 0.24464
