A boat is moving along the water. The forward thrust from the engines is 35,000 N. Water resistance is 20,000 N and air resistance 10,000 N. What is the resultant force on the boat?

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

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
