Suppose you are navigating a spacecraft far from other objects. The mass of the spacecraft is 4.0 x 10 kg (about 40 tons). The rocket engines are shut off, and you're coasting along with a constant velocity of <0, 22,0 km/s. As you pass the location < 6, 9, 0 km you briefly fire side thruster rockets, so that your spacecraft experiences a net force of < 6.0 x 105, 0, 0> N for 22.5 s. The ejected gases have a mass that is small compared to the mass of the spacecraft. You then continue coasting with the rocket engines turned off. Where are you an hour later? (Think about what approximations or simplifying assumptions you made in your analysis. Also think about the choice of system: what are the surroundings that exert external forces on your system?) 74= m

While walking on water, an arctic wind freezes the water beneath your feet and you now find yourself stuck in the middle of a 15m diameter lake on top of a frictionless layer of ice. Unable to just walk off, you decide to push off your physics book with a force of 80.0N for 0.1s. How long in minutes will it take you to reach the shore if your mass is 75kg?
(a) Find the speed at which Superman (mass=90.0 kg) must fly into a train (mass = 17485 kg) traveling at 65.0 km/hr to stop it. Running into the train at that speed would severely damage both train and passengers. (b) Calculate the minimum time Superman must take to stop the train if the passengers experience an average horizontal force of 0.410 their own weight. (c) How far does the train then travel while being slowed to a stop?
How come in free fall you feel weightless even though gravity is pulling down on you? (ignore air resistance when answering this question).
A 747 jetliner lands and begins to slow to a stop as it moves along the runway. If its mass is 3.56×105 kg, its speed is 73.0 m/s, and the net braking force is 4.30×105N, what is its speed 12.0 s later? How far has it traveled in this time?
A flea jumps by exerting a force of 1.20×10−5 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 0.500×10−6 N on the flea. (a) Find the direction of the acceleration (relative to the +y axis) of the flea if its mass is 6.00×10−7 kg. Do not neglect the gravitational force.
Mary applies a force of 77 N to push a box with an acceleration of 0.55 m/s2. When she increases the pushing force to 85 N, the box's acceleration changes to 0.71 m/s2. There is a constant friction force present between the floor and the box. (a) What the mass of the box in kilograms? kg (b) What is the coefficient of kinetic friction between the floor and the box?

A constant force acting on a body of mass 3.0 kg changes its speed from 2.0 ms-1 to 3.5 ms-1 in 25 s. The direction of the motion of the body remains unchanged. What is the magnitude and direction of the force?
A certain aircraft has a mass of 300,000 kg. At a certain instant during its landing, its speed is 27.0 m/s. If the braking force is a constant 445,000 N, what is the speed of the airplane 10.0 s later?
The rocket in a rocket-powered airplane generates a steady force of 10,000 N in the forward direction and the plane moves horizontally at a constant velocity of 300 m/s through the air. The rocket engine is upgraded so that it now provides a forward force of 90,000 N. What is the new constant velocity of the plane? You cannot neglect air resistance in this question. 200 m/s 300 m/s 400 m/s 600 m/s 900 m/s
A "doomsday" asteroid with a mass of 1.0 × 1010 kg is hurtling through space. Unless the asteroid's speed is changed by about 0.25 cm/s, it will collide with Earth and cause tremendous damage. Researchers suggest that a small "space tug" sent to the asteroid's surface could exert a gentle constant force of 2.4 N . For how long must this force act?
Walking in Waikiki, a tourist steps out onto Kuhio Dr while texting. Unbeknownst to the sunburned visitor, the street has been closed for the filming of a car chase scene for Hawaii 5-0. Slamming on the breaks, the stunt driver is thrown against his seatbelt, stopping in 90m. If the driver and the car weigh a total of 544kg and were traveling at 18 m/s, what force does the 90kg driver feel? Sketch: Equations: Work:
