I WANT QUESTIONS RELATED TO THE CHAPTER MOTION. I WANT ONLY NUMRICALS TYPE QUESTION.

IF U HAVE QUESTIONS
THEN ANSWER

Answer 1

1. An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the distance traveled before takeoff.
2. A Jeep starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of    110m. Determine the acceleration of the Jeep.
3. John is riding the Giant Drop at Canada. If John free falls for 2.6 seconds, what will be his final velocity and how far will he fall?
4. Aeronautics engineer is designing the runway for an airport. Of the planes that will use the airport, the lowest acceleration rate is likely to be 3 m/s2. The takeoff speed for this plane will be 65 m/s. Assuming this minimum acceleration, what is the minimum allowed length for the runway?

Answer 2

OK take this :-

1.An object has moved through a distance.can it have zero displacement? If yes, support your answer.

2.A farmer moves along the boundary of a square field of side 10m in 40s. what will be the magnitude of displacement of the farmer at the end of 2min 20s from the initial position?

3.A man travel a distance of 1.5m east, then 2.0m south and finally 4.5m east, first distance travell

a) what is its final displacement?

4.A car covers a distance of 3km in 5min. calculate the speed of car:

a) centimeter per second (cm/s)

b) meter per second (m/s)

c) kilometer per hour (km/ h)

5.A train-A travell a distance of 120km in 3h. whereas train-B travell a distance of 180km in 4h. which train travell faster.

6.A car travell 30 km at a uniform speed of 40km/h and next 30km at a uniform speed of 20km/h. Find its average speed.

7.An object travell 16m in 4s and then another 16m in 2s. What is the averge speed of the object?

8. A train travell a speed of 60km/h for 0.52h at 30km/h for next 0.24h and then at 70km/h for next 0.71h. what is the average speed of the train .

hope it help
