Suppose the mass of a fully loaded module in which astronauts take off from the Moon is 13,800 kg. The thrust of its engines is 25,000 N. (Assume that the gravitational acceleration on the Moon is 1.67 m/s2.)   Calculate (in m/s2) its magnitude of acceleration in a vertical takeoff from the Moon. (Enter a number.)     Could it lift off from Earth? If not, why not? No, the thrust of the module's engines is less than its weight on Earth. Yes, the thrust of the module's engines is equal to its weight on Earth.     No, the thrust of the module's engines is equal to its weight on Earth. Yes, the thrust of the module's engines is greater than its weight on Earth.     If it could, calculate (in m/s2) the magnitude of its acceleration. (Enter a number. If not possible, enter NONE.)

A jet aircraft with a mass of 4,650 kg has an engine that exerts a force (thrust) equal to 60,800 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

You are standing on a bathroom scale in an elevator (yes people are staring at you).  You weigh 50 kg but the scale reads in Newtons. Weight (force of Gravity) = Mass x Gravity (10m/s2) As the elevator comes up on the ground floor it decelerates at 2 m/s2 downward.    What is the Gravitational Force?     Since the elevator is decelerating downward does the Normal Force have to be greater than, equal to or less than the Force of Gravity?     Are the forces balanced or unbalanced?     Draw a free body diagram of the forces acting on you.  Be sure to draw the size of your arrows appropriately.     What is the Net Force, using Newton’s 2nd Law, while the elevator is decelerating downward?     What is the Normal Force?     What does the scale read as the elevator is decelerating downward?     What pattern did you notice occurred between all of the different scenarios?

As you go above the Earth's surface, the acceleration due to gravity will decrease. Find the height, in (meters), above the Earth's surface where this value will be 1/150 g.

A parachuter of mass 139 kg above Earth (g = 10 m/s2) experiences a drag force modeled by -0.04 v (N).  If the parachuter is released from rest, how fast, in m/s, will the jumper be falling after 1,027 s? (Assume the parachuter doesn't reach the ground in this amount of time.)(I want the speed.) (Please answer to the fourth decimal place - i.e 14.3225)

A student has a mass of 25 kg.  If he stands on a scale in an elevator that is accelerating downward at 2.0 m/s/s, what will be his apparent weight?

Part A Comets travel around the sun in elliptical orbits with large eccentricities. If a comet has speed 2.1×104 m/s when at a distance of 2.6x1011 m from the center of the sun, what is its speed when at a distance of 4.0×1010 m. Express your answer in meters per second. Πνα ΑΣΦ m/s

The separation distance between two 1.0 kg masses is changed. How is the mutual gravitational force affected in each case? (Assume F2 represents the new force and F1 represents the original force.) (a) The separation distance is two-fifths the original distance.F2 / F1 =  (b) The separation distance is 8 times the original distance.F2 / F1 =

A jet aircraft with a mass of 4,375 kg has an engine that exerts a force (thrust) equal to 59,900 N. (a) What is the jet's acceleration when it takes off? (Give the magnitude.) m/s? (b)What is the jet's speed after it accelerates for 7 s? (Assume it starts from rest.) m/s (c) How far does the jet travel during the 7 s?

You are an astronaut exploring an unknown planet, with a mass of 4.02×1024 kg, and a radius of 4,148 km.  Draw a free body diagram of the forces acting as you stand on the surface. What is the magnitude of the acceleration due to gravity at the surface of the planet in m/s2?  Calculate your answer to 2 sf.
