A rocket with a mass of 2.75 x 106kg exerts a vertical force of 3.55 x mm on the gases it expels. Determine: The acceleration of the rocket 3.1 m/s'2 Its velocity after 8 seconds 25m/s How long it takes to reach an altitude of 9500m 78s Suppose that a 1000kg car is traveling at 25m/s. Its brakes cause a 5000N net force to be applied to the car. What is the minimum distance required for the car to stop? A race car has a mass of 710kg. It starts from rest and travels 40m in 33. The care accelerates uniformly during the entire time. What net force is acting on the car? 6912N HA
