The average speed of a nitrogen molecule in air is about 6.70 × 102 m/s, and its mass is 4.68 × 10−26 kg. (a) If it takes 3.00 × 10−15 s for a nitrogen molecule to hit a wall and rebound with the same speed but moving in the opposite direction, what is the average acceleration of the molecule during this time interval? (b) What average force does the molecule exert on the wall?

- A freight train consists of two 8.00×104 kg5.60×104 kg engines and 45 cars with average masses of 5.50×104 kg5.50×104 kg. (a) What force must each engine exert backward on the track to accelerate the train at a rate of 4.00×10−2 m/s if the force of friction is 6.20×105 N, assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains is small, and consequently trains are very energy-efficient transportation systems. (b) What is the force in the coupling between the 37th and 38th cars (this is the force each exerts on the other), assuming all cars have the same mass and that friction is evenly distributed among all of the cars and engines?arrow_forwardA horizontal force of 12 N pushes a 0.50-kg book against a vertical wall. The book is initially at rest. If = 0.60 and = 0.50, the acceleration of the book is (in meter per second squared)arrow_forwardAbout 80 g of blood is pumped from the heart during each heartbeat. The blood starts at rest and has a speed of about 0.60 m/s in the aorta. If the pumping takes 0.17 s, What is the magnitude of the average force on the blood?arrow_forward
- The average speed of a nitrogen molecule in air is about 686 m/s, and its mass is 4.85 x10-26 kg. If it takes 3.78 x 10-13 s for a nitrogen molecule to hit a wall and rebound with the same speed but moving in the opposite direction, what is the magnitude of the average acceleration of the molecule during this time interval?arrow_forwardThe average speed of a nitrogen molecule in air is about 6.70 x 102 m/s, and its mass is 4.68 3 10-26 kg. (a) If it takes 3.00 x 10-13 s for a nitrogen molecule to hit a wall and rebound with the same speed but moving in the oppositedirection, what is the average acceleration of the molecule during this time interval? (b) What average force does the molecule exert on the wall?arrow_forwardThe highest spot on Earth is Mt. Everest, which is 8850 m above sea level. If the radius of the Earth (to sea level) is 6370 km, how much does the magnitude of g change between sea level and the top of Mt. Everest? (G = 6.67 × 10-11 N m2/kg2, and the mass of the Earth is 5.98 × 1024 kg.)arrow_forward
- A box of mass 10.2 kg is slid along the floor. The initial speed of the box is 2.5 m/s and it comes to rest after 8.1 m. What was the magnitude of the force of friction acting on the box during this motion? You must enter you answer and include the SI units. (For example: 3.0kg)arrow_forwardA spring is compressed between two blocks, one with a mass of 2 kg and the other with a mass of 3 kg. If the 2 kg block has an average acceleration of 6 m/s^2 when the spring acts on it, what will be the average acceleration of the 3 kg block?arrow_forwardAn object has a velocity (4.69 m/s)i + (-4.4 m/s)j + (4.73 m/s)k. In a time of 5.5 s its velocity becomes (-2.22 m/s)i + (0.00 m/s)j + (4.73 m/s)k. 1) If the mass of the object is 3.31 kg, what is the magnitude of the net force on the object, in N, during the 5.5 s? Assume the acceleration is constant.arrow_forward
- 6) The average speed of a nitrogen molecule in the air is about 6.70 X 102 m/s, and its mass is 4.68 X 10-26 kg. (a) If it takes 3.00 X 10-13 s for a nitrogen molecule to hit a wall and rebound with the same speed but moving in the opposite direction, what is the average acceleration of the molecule during this time interval? (b) What average force does the molecule exert on the wall?arrow_forwardA mass of m₂ = 50 kg is a fixed distance dw = 6 m to the west and a distance dy = 11 m to the north of a mass, m₁. Mass m₂ exerts a force of magnitude F = 3.2 × 10-8 N on m₁. 1) What is the mass of m₁? m₁ = 345 kg m₁ = 120 kg m₁ = 1510 kg 2.37 x 105 kg m₁ = m₁ = 1160 kgarrow_forwardAn investigation of an automobile crash suggests that vehicle A was moving at 52 mph toward the south and vehicle B was moving at an unknown speed toward the north, when the two cars collided, sticking together after the collision. Vehicle A weighs 1350 lbs., and vehicle B weighs 1893 lbs. If the cars did not move significantly after their collision, find the initial speed of vehicle B in mph. Answer: mph (miles per hour)arrow_forward
