- What external force is responsible for changing the momentum of a car moving along a horizontal road?Which has a greater amount of Momentum? A 10 kg cannonball flying at 350 m/s, or a 1000 kg car rolling at 3 m/s? OThe cannonball OThey have the same amount of momentum O Neither of them has any momentum The carcalculate the average momentum of a 50-kg runner if she can finish a 5-km run in 30 minutes
- A whiffle ball moving upward passes three identically sized windows as shown. Rank from greatest to least the whiffle ball's displacement, magnitude of change in momentum, and acceleration across each window. Neglect air resistance.In terms of impulse and momentum, why are nylon ropes, which stretch considerably under tension,favored by mountain climbers?How much impulse is needed to stop a 25kg bowling ball rolling at 9m/s?
- Gabi shoots his rifle on a bird sitting on top of the tree as shown. The bird has a mass of 10kg and that of the rifle's bullet is 50 grams. Speed of the bullet is 300m/s.A box a thrown horizontally out of the window with a velocity of 15.5 m/s. If the window is 1.7 m above the ground, how far will the box travel before it hits the ground? Show complete solution. How much impulse is produced if a ball is thrown with a force of 80 N and travelled for 2 minutes?(a) State the Law of Conservation of Momentum. Deduce it from Newton’s second law of motion. (b) Give reason for the following: (i) An air-filled balloon rise up slightly when punctured from below? (ii) A swimmer push water backward with his hands, in order to swim in forward direction?
- A 5-kg fish swallows an absentminded 1-kg fish swimming towards it at a velocity that brings both fish to a halt immediately after lunch. What is the velocity of the smaller fish before it becomes lunch? (The speed of the big fish is not given but similar questions give the big fish a 1 m/s velocity) (The question has to do with the conservation of momentum)In Chapter 5, rocket propulsion was explained in terms of Newton’s third law. That is, the force that propels a rocket is from the exhaust gases pushing against the rocket, the reaction to the force the rocket exerts on the exhaust gases. Explain rocket propulsion in terms of momentum conservation.A 25-g bullet traveling horizontally at 210 m/s penetrates a stationary 3-kg block of wood resting on a table and emerges with a velocity of 100 m/s. What is the velocity of the block after the bullet emerges? Show that kinetic energy is not conserved.
