As seen in the picture, an airboat is a special type of boatthat has a large fan mounted on the back instead of a motorthat sits in the water. It is used in places where the water isshallow and weedy, so motors that stick down into the watercannot be used. a) Using Newton’s Third Law, explain why the fan needs tobe pointed so the air blows out backwards. b) If the force of the fan pushes the air backwards with 150 N, what is the forward force ofthe air on the boat? If the mass of the boat is 220 kg, and you ignore friction between theboat and the water, find how far the boat will travel in the first minute. c) How can the fan on the airboat be used to change the direction the boat is travelling in?How can it be used to increase or decrease the speed of the boat? d) If the boat is going upstream against a current that has a force of 250 N against themotion of the boat, find the acceleration of the boat if there is a forward force of 360 N fromthe fan. (Remember that the mass of the boat…

Two masses, m1 and m2 are connected by a frictionless pulley and a massless string (idealpulley system). One mass, m1 sits on a 25o incline that is also frictionless, the other mass issuspended in air, as shown in figure 2. The mass on the incline (m1) has a mass of 5kg. Bothmasses are at rest.a) Draw a free-body diagram for both masses.b) What is the value of m2?
When an object falls freely under the influence of gravity there is a net force mg exerted on it by the Earth. Yet by Newton's third law the object exerts an equal and opposite force on the Earth. Does the Earth move? Explain your answer in words.
