if somebody help me pls.give me word problems about motion/distance i need at least 10 or as many as you can.?

Answer 1

1. Rig a mechanism to fire a 2 pound (or 1 kg if working metric) ball from a level of 3 feet above ground to a point exactly 60 feet (20 m) away. What is the force required and what is the angle of launch? (yes the answers are different for American and Metric and yes, the force differs with the angle for the same distance.)
2. Whoops, the ground slopes from 3 feet (1 m) in front of the launch point falling away at 1.5 foot (.5 m) every 10 feet.(3 m) Change the force to land the ball at exactly 60 feet (20 m) horizontally (and down X feet (m)) out. If you can, keep the force the same and change the angle. (depending on the angle you chose in 1 you may not be able to.)
3. In problem 1, there is a rail line running through the aiming point going straight away. We notice a car traveling 30 ft/sec (10 m/sec) away from us and fire exactly as its nose crosses the 60 ft (20 m) point. What changes must be made to hit the car and ABOUT how much force or angle must be used. Figuring the exact time may be too complicated, especially if you aim for the nose.
4. In problem 2, the rail line slopes downward and again we notice the car and fire as it crosses the 60 ft (20 m) point. Adjust the firing for the car going 30 ft/sec (10 m/s) at that point and being accelerated by standard gravity.
5. In problem 4, the car starts at the beginning of the track at zero speed accelerating under the force of gravity, but we are not able to fire until it crosses the trigger point at 60 ft (10 m) out. Determine its speed there and determine where and when we will have to aim to hit it and a force and angle to get the ball there.
That's five. Too much complication?

Answer 2

a million. Eddie is two years older than Eric. The sum of their an prolonged time is 20. discover their present day an prolonged time. 2. Agnes is 3 years older than Bobby. The sum of their an prolonged time is fifty 3. How previous have been they 7 years in the past? 3. Monette is three hundred and sixty 5 days older than two times her brother's age. the version of their an prolonged time is eighteen. discover their present day an prolonged time. 4. Janice is now 4 circumstances as previous as her brother Ogie. In 4 years, Janice's age would be two times Ogie's age then. How previous is each and each now? 5. My mom is now 40 years previous and my sister is 14 years previous. In how some years will mom be precisely two times as previous as my sister? 6. The sum of Jackie's age and Celine's age is 20. Jackie's age three hundred and sixty 5 days from now would be 9 circumstances Celine's age three hundred and sixty 5 days in the past. How previous is each and each now? 7. Alfred replaced into 25 years previous whilst his daughter replaced into born. His present day age is 7 years below three times his daugter's age. How previous is Alfred now? 8. Father replaced into 28 years previous whilst uncle John replaced into born. The sum of their an prolonged time is 80 4. How previous is uncle John? 9. Jonathan is 3 extra desirable than two times the age of Vincent. In ten years, the sum of their an prolonged time would be 40 seven. How previous are they 5 years hence? 10. Carlo is three times Nadine's age. In 3 years, he would be two times Nadine's age then. discover their present day an prolonged time.
