Question

Sample B Block B begins with an initial velocity of 2.5 m/s. If the kinetic friction between block A and the horizontal plane is 0.25 and the mass of the pulleys and cord is neglected, determine: 1) the tension in the cord and the accelerations of each block. 2) The final velocity of block B after 2 s.

Step 1

- The frictional force is μN = 0.25 * m * g, where m is the mass of block A and g is the acceleration due to gravity (9.81 m/s^2). - The net force is T - 0.25 * m * g. - The acceleration of the system is given by a = (T - 0.25 * m * g) / (m + m), since both blocks Show more…
