50. Consider a mass of 1 kg accelerated 1 m/s2 by a force of 1 N. Show that the acceleration would be the same for a force of 2 N acting on 2 kg. 51. Consider a business jet of mass 30,000 kg in takeoff when the thrust for each of its two engines is 30,000 N. Show that its acceleration is 2 m/s2.
The thrust produced by a single jet engine creates a force of F = 84000 N. It takes the jet (with a mass of m = 5200 kg) a distance of d = 0.78 km to take off. What is the take-off speed of the jet vt in m/s? How far in meters would you need to depress a giant spring k = 100,000 N/m in order to launch the jet at the same speed without help from the engine?

Sam, whose mass is 80 kg , takes off across level snow on his jet-powered skis. The skis have a thrust of 220 N and a coefficient of kinetic friction on snow of 0.1. Unfortunately, the skis run out of fuel after only 10 s .How far has Sam traveled when he finally coasts to a stop?
A jet weighing 22 tons must be moving at 210 mi/h to take off. What is the minimum thrust (in pounds) that the jet's exhaust must exert on its engines if the plane is to successfully take off from a 420 foot airstrip? [1 m/s=2.24 mi/h, 1 mi=5280 ft, 1 ton=2000 lbs]
A jet aircraft with a mass of 4,675 kg has an engine that exerts a force (thrust) equal to 59,500 N. (a) What is the jet's acceleration when it takes off? (Give the magnitude.) m/s2 (b)What is the jet's speed after it accelerates for 9 s? (Assume it starts from rest.) m/s (c) How far does the jet travel during the 9 s? m
Sam, whose mass is 80 kg takes off across level snow on his jet-powered skis. The skis have a thrust of 200 N and a coefficient of kinetic friction on snow of 0.1. Unfortunately, the skis run out of fuel after only 15 s. What is Sam's top speed? Express your answer to two significant figures and include the appropriate units. How far has Sam traveled when he finally coasts to a stop? Express your answer to two significant figures...
Sam, whose mass is 75 kg , takes off across level snow on his jet-powered skis. The skis have a thrust of 160 N and a coefficient of kinetic friction on snow of 0.1. Unfortunately, the skis run out of fuel after only 15 s . A: What is Sam's top speed? - I found the answer to be 17 m/s (can you check this for me?) B: How far has Sam traveled when he finally coasts to a stop?...
A jet plane with a mass of 363000 kg travels east at 936 km/hr. Air resistance exerts a force of 936 kN to the west, while the jet engines provide a thrust on the airplane of 936 kN to the east. What is the change in the plane's horizontal velocity after 397 s?
Concept: Work-Energy Theorem Qu. 1 A fighter jet is launched from an aircraft carrier with the aid of its own engines and a steam powered catapult. The net thrust of its engines is 2 x 10' N. In being launched from rest it moves through a distance of 90 m and has a kinetic energy of 4 x 10'J at lift-off. a) Draw a diagram identifying the forces and a coordinate system (5 points) b) What is the work done...
