A 1.00 × 10º-N crate is being pushed across a level floor at a constant speed by a force É of 3.00 x 10² N at an angle of 20.0° below the horizontal, as shown in Figure P4.23a. (a) What is the coefficient of kinetic friction between the crate and the floor? (b) If the 3.00 × 10²N force is instead pulling the block at an angle of 20.0° above the horizontal, as shown in Figure P4.23b, what will be the acceleration of the crate? Assume that the coef- ficient of friction is the same as that found in part (a). 20.0° 120.0° Figure P4.23
