A72 kg sled is pulled forward from rest by a snowmobile and accelerates at 2.0m/s^2( forward) for 5.0 seconds. the force of friction acting on sled is 120 n (backwards). the total mass of a snowmobile and driver is 450 kg. the drag force acting on snowmobile is 540 n (backwards). determine the tension in the rope and the force exerted by the snowmobile that pushes the sled forward.

Tension force in the rope is 264 N

Force exerted by snowmobile is 1704 N

Explanation:

For sled there is tension force on it in forward direction and friction force on it in backward direction

So here we will have

as we know

now for snowmobile and driver we know that their total mass is

m = 450 kg

drag force on it is in backward direction as 540 N

there is tension force on it in backward direction is T = 264 N

now the net force of it is given by

i don't understand. explain it clearly
