A 5 kg block accelerates across a horizontal surface at 7 m/s^2 when you exert a 60 N force on it. What is the force of friction on the block (Ffs/b)?
If you don’t mind finding the kinetic friction coefficient too?

Check the following equation for dimensional homogeneity: ⅆ mv=∫t1t2(f⁢cosθ)ⅆt where m is mass, v is velocity, f is force, θ is an angle, and t is time. check that each term in the equation has the following dimensions: [malbec] where you are to choose the coefficients a, b, c.
