The equation for momentum is shown below: p=m×v Where... p = momentum (in kg·m/s), m = mass (in kg), and v = velocity (in m/s) SHOW WORK 1. Calculate the momentum of a 0.145 kg baseball being thrown at a speed of 40.0 m/s. 2. If a 6.0 kg bowling ball is rolled with a velocity of 3.5 m/s, what is the momentum of the ball? 3. Which has more momentum, a 3.0 kg mass moving at 9.0 m/s or a 5.0 kg mass moving at 5.0 m/s? 4. A bicycle has a momentum of 25.00 kg·m/s and a velocity of 2.5 m/s. What is the bicycle’s mass? 5. What is the velocity of a 0.5 kg ball that has a momentum of 3.00 kg·m/s? 6. An 8000.0 kg truck starts off from rest and reaches a velocity of 18.0 m/s in 6.00 seconds. What is the truck’s acceleration and how much momentum does it have after it has reached this final velocity? STATION 6: Science Riddles We’ve talked about the answers to all of these at some point in time. Try to get as many as you can 1. You cannot see me, I cannot be touched, you cannot feel me but I can cook your lunch. What am I? 2. What is a Priest's favorite part about Physics? 3. Which is heavier, a pound of feathers or a pound of bricks? 4. I can rush, I can be hot, I can be cold, I can be hard, I can slip through anything. What am I? 5. It is impossible for me to be created, and I can never be destroyed, I can only change form. What am I? 6. You can't see me, but I can see right through you. Especially when you are hurt. What am I? 7. What can eat a lot of iron without getting sick? 8. What can be measured but has no width, length or height? 9. Give me food and I will live. Give me water and I will die. What am I? 10. In space I’m massive and solid as rock, on earth (at room temperature) I am a little puddle. What am I? 11. I am a gas and line-up with neon. I am also the home of a superhero. What am I?
