PHYS 102 Module 2 CH 2 HW (Homework)

1. 6.66/7.14 points | Previous Answers A jet aircraft with a mass of 4,250 kg has an engine that exerts a force (thrust) equal to 60,400 N. (a) What is the jet's acceleration? (Give the magnitude.) 14.21 m/s^2 (b)What is the jet's speed after it accelerates for 7 s? (Assume it starts from rest.) 99.47 m/s (c) How far does the jet travel during the 7 s? 348.15 m Show My Work (Optional) 2. 7.14/7.14 points | Previous Answers A motorcycle and rider have a total mass equal to 330 kg. The rider applies the brakes, causing the motorcycle to accelerate at a rate of What is the net force on the motorcycle? (Indicate the direction with the sign of your answer.) -2640 N Show My Work (Optional) 3. 7.14/7.14 points | Previous Answers In an experiment performed in a space station, a force of 59 N causes an object to have an acceleration equal to 6 m/s 2. What is the object's mass? 9.83 kg Show My Work (Optional) 4. 7.14/7.14 points | Previous Answers On aircraft carriers, catapults are used to accelerate jet aircraft to flight speeds in a short distance. One such catapult takes a 17,700kg jet from 0 to 65 m/s in 2.9 s. (Assume the catapult acts in the positive horizontal direction. Indicate the direction with the sign of your answer where appropriate.) (a) What is the acceleration of the jet in m/s2? +22.41 m/s^2 (b) What is the acceleration of the jet in g's? 2.29 g (c) How far does the jet travel while it is accelerating? 94.23 m (d) How large is the force that the catapult must exert on the jet? N Show My Work (Optional) 5. 7.14/7.14 points | Previous Answers An airplane is built to withstand a maximum acceleration of 5 g. If its mass is 1,590 kg, what size force would cause this acceleration? 77910 N Show My Work (Optional) Module 2 CH 2 HW (Homework) Valerie Hallet Instructor: William Beston W
