Ablock with mass m1 94 kg is on an incline with an angle , Ask an Expert

Academics

A block with mass m1 = 9.4 kg is on an incline with an angle ? = 24.0° with respect to the horizontal. For the first question there is no friction, but for the rest of this problem the coefficients of friction are: ?k = 0.23 and ?s = 0.253. * When there is no friction, what is the magnitude of the acceleration of the block? m/s2 * Now with friction, what is the magnitude of the acceleration of the block after it begins to slide down the plane
