Following IIT JEE Entrance Multiple choice objective type questions and answers will help you in Maths, Physics and Chemistry 2024 examinations :
1.During the shooting of a super hit film MARD Amitabh Bachchan was waiting for his beloved Amrita Singh with his dog. When he saw her approaching, the dog was excited and dashed to her than back to master and so on, never stopping. How far would you estimate the dog ran if its speed is 30 km/h and each of them walked at 4 km/h, starting from a distance 400m apart? |
| 400m |
| 880m |
| 1500m |
| 30 km |
2.A car moving with a speed of 50 km/h, can be stopped by brakes after at least 6m. If the came car is moving at a speed of 100 km/h, the minimum stopping distance is: |
| 12m |
| 18m |
| 24m |
| 6m |
3.A person walks up a stalled escalator in 90s. When standing on the same escalator, now moving, he is carried in 60s. The time it would take him to walk up the moving escalator will be: |
| 27 s |
| 72 s |
| 18 s |
| 36 s |
4.Speed is to velocity as: |
| centimeter is to metre |
| force is to torque |
| velocity is to acceleration |
| distance is to displacement |
5.An object moves, starting from rest through a resistive medium such that its acceleration is related to velocity as a = 3 � 2v. Then: |
| the terminal velocity is 1.5 unit |
| the terminal velocity is 3 unit |
| the slope of a-v graph is not constant |
| initial acceleration is 2 unit |
