Math Problem Statement
A wheel with mass m = 3 kg, radius R = 0.3 m rolls on a flat surface under the influence of a force F = 4 N applied to the center of the wheel and directed parallel to the plane. Initial speed V0=2m/s. Rolling friction coefficient K1=0,016. Sliding friction coefficients K2=0.6. Find the linear, angular velocity and acceleration of the wheel after 5 s, 10 s.

Formulas
F_net = F - f_rolling
f_rolling = K1 * m * g
a_linear = F_net / m
τ = f_rolling * R
I = (1/2) * m * R^2
α = τ / I
V(t) = V0 + a_linear * t
ω(t) = ω0 + α * t
ω0 = V0 / R
