Problem Information: The A team is still falling in a tank and have 90 seconds before they reach the ground. Their tank has a mass of 62,000 kg (with all ammunition inside) and it fires 20 kg shells at 1,500 m/s. Assume it starts with a constant downward velocity of 15 m/s. They need to slow down to 5 m/s to survive. To do this they fire the tank downwards. Remember to use the formula: M₁V₁¡ + m₂V₂i = m₁V1f + m₂V2f Problems: 5. At its starting velocity, how far will the tank fall in 90 seconds? English (U.S.) 6. What is the momentum of the tank before it fires? 7. If the A-team fires one shell downward, what will their new velocity be? Before Firing Text Predictions: On Editor Suggestions: Showing DELL After firing + 127% Fit x C

You find yourself stuck in outer space with nothing but your physics book and a space suit. You have a mass of 91 kg in your suit, and your physics book has a mass of 2.3 kg. In order to make it back to your stationary spaceship before running out of air, you must move at 0.18 m/s. How fast (in m/s) do you have to throw your physics book to achieve this speed?
Two identical cars, A and B, traveling at 55 mi/h collide head-on. A third identical car, C, crashes into a brick wall going 55 mi/h. Which car has the least damage: (a) car A, (b) car B, (c) car C, or (d) all the same? Why is the answer C?
A 2,800 kg truck jumps the median and clobbers a 940 kg station wagon in a head-on collision. You are tasked with determining the truck's initial speed for insurance purposes. An observer states that the station wagon was traveling at a speed of 25.1 m/s and that after the collision, the two vehicles stuck together and were moving at a speed of 24.4 m/s in the direction the truck was originally moving. What was the truck's original speed?
The Hulk (200kg of pure angry muscle)collides head-on with a truck (2500kg). If the Hulk was running at 10.0m/s and the truck was moving at 15.0 m/s in the opposite direction, after they stick together, what is their speed (in m/s)? Either the Hulk or the truck needs a negative initial velocity.
Lark Brandt won a "Worlds Fastest Smash" competition in the early 2000s. His ping pong ball achieved a speed of 112.5 km/hr. If his ping pong ball had a mass of 2.7 g and hit a wooden block with a mass of 125 g and bounced back with a speed of 45.0 km/hr, what speed (in km/hr) would the wooden block have?
4. A 3 kg mass slides down an inclined plane that has an angle of 25 degrees. It starts at rest and travels a distance of 16 meters. What is its final velocity if Hk=0.15?

Sherlock Holmes is one of the most famous detectives in fiction literature. Even with limited resources to solve crime in the 1800-1900's, Holmes could solve countless mysteries. A carriage was North-bound traveling at a leisurely pace of 5 km/hr. It collided with a Westward-bound speeding carriage and they stuck together, skidding across the dirt at an North-West direction away from the point of collision. What physics law(s) does Sherlock use to solve this mystery? Conservation of Momentum Conservation of Energy Conservation of Angular Momentum Both Conservation of Momentum and Energy OOO O
