A 350-kg sailboat has an acceleration of 0.62 m/s2. Find the net force that acts on the sailboat

An airplane has a mass of 31000 kg and takes off under the influence of a constant net force of 37000 N. What is the net for that acts on the 78 kg pilot?

In the amusement park ride known as Magic Mountain Superman, powerful magnets accelerate a car and its riders from rest to 45 m/s (about 100 mph) in a time of 7.0 s. The mass of the car and riders is 5500 kg. Find the average net force exerted on the car and riders by the magnets. (Hint - you have to find acceleration first)

A person with a black belt in karate has a fist that has a mass of 0.70 kg. Starting from rest, this fist attains a velocity of 8.0 m/s in 0.15 s. What is the magnitude of the average net force applied to the fist to achieve this level of performance?

A 1580-kg car is traveling with a speed of 15.0 m/s. What is the magnitude of the net force that is required to bring this car to a halt in a distance of 50.0 m? (Hint you have to find the time it takes to stop first. Remember that average velocity is half of the change in velocity.)

When a 58-g tennis ball is served, it accelerates from rest to a speed of 45 m/s. The impact with the racket gives the ball a constant acceleration over a distance of 44 cm. What is the magnitude of the net force acting on the ball? (Careful the distance is in cm not in m and the mass is in g not kg)
