Answer:
The resultant force on the boat is 5,000 N
Explanation:
Given;
the forward thrust on the boat, Ft = 35,000 N
water resistance on the boat, Fw = 20,000 N
Air resistance on the boat, Fa = 10,000 N
The forces opposing the boat motion will be negative, while the force pushing the boat forward will be positive
The resultant force on the boat, Fr = Ft - Fw - Fa
Fr = 35,000 N - 20,000 N - 10,000 N
Fr = 35,000 N - 30,000 N
Fr = 5,000 N
Therefore, the resultant force on the boat is 5,000 N
