A team of dogs pulls two dog sleds across a frozen pond. The sled at the front has an unknown mass m2 and the sled at the back has a mass of 150 kg The ropes attached to the dogs form an angle of 16 with the horizontal and the dogs pull with a constant force of 160 N. While the sleds are being pulled, the front sled experiences a normal force of 840 N and the tension in the horizontal rope connecting the two sleds is T. All forms of friction can be ignored. 160 N M₂ sleds T 150 kg CTI Front Back 7.1. Draw labelled free-body diagrams indicating all the forces acting on both of the sleds as they are pulled by the dogs. 7.2. Calculate the mass of the front sled, m₂. (Ans.: 90,2 kg) 7.3. Calculate the acceleration of the sleds as well as the tension in the rope connecting the two (Ans.: a = 0,64 ms, T=96,04 N)​
