In the figure masses m_(1),m_(2) and M are kg. 5 kg and 50 kg respectively. The co-efficient of friction between M and ground is zero. The co-efficient of friction between m_(1) and M and that between m_(2) and ground is 0.3. The pulleys and the string are massless. The string is perfectly horizontal between P_(1) and m_(1) and also between P_(2) and m_(2). The string is perfectly verticle between P_(1) and P_(2).
