Force & motion – numerical problems
1. A car travels a distance of 30 km in 20 minutes towards the east. Calculate the velocity of the car.
2. A person takes 8 minutes to cover a distance of 15 km in his car. Calculate the average velocity of his car.
3. Two vehicles X & Y are moving in the same direction with the velocity of 12 m/s & 6 m/s respectively. Calculate the relative velocity of X with respect to Y. If both vehicles are travelling in the opposite direction, what will be the relative velocity?
4. Two vehicles X & Y are moving with the velocity of 20 m/s towards east & 12 m/s towards west respectively. If they started from the same place & the same time, calculate the distance between them after 2 minutes.
5. Calculate the acceleration of a truck if it starts from rest & attains a velocity of 25 m/s in 5s.
6. A car starts from rest & attains an acceleration of 4 m/s2 after 10 seconds. Calculate the distance covered by the car.
7. A bus starts to move from rest & attains an acceleration of 0.5 m/s2. Calculate the final velocity of the bus after 50 seconds & distance covered by the bus within that time.
8. Two vehicles X & Y are moving in the same direction with the velocity of 12 m/s & 8 m/s respectively. Calculate the relative velocity of X with respect to Y. Also, calculate the relative velocity when they are moving in opposite directions.
9. Two vehicles are moving, one with the velocity of 20 m/s towards east & another with 10 m/s towards west. Calculate the distance between them after 20 minutes if they are started from the same place & the same time.
10. If a body starts from rest & attains a velocity of 20 m/s in 8 seconds, calculate the acceleration produced on the body.
11. A vehicle is running at a speed of 45 km/hr. If it is stopped in 3 seconds by applying the brakes, calculate the retardation of the vehicle & the distance travelled before its stopping.
12. The velocity of a moving body increases from 10 m/s to 15 m/s in 5 seconds. Calculate its acceleration.
13. A body moving along a straight path at a velocity of 20 m/s attains an acceleration of 4 m/s2. Calculate the velocity of the body after 2 seconds.
14. A vehicle was moving at a speed of 90 km/hr. On seeing a baby 20 m ahead on the road, the driver jammed on the brakes & it came to rest at a distance of 15m. What is its retardation & how long does it take to come at rest ?
15. A body starts moving from rest & attains the acceleration of 0.5 m/s2. Calculate the velocity at the end of 3 minutes. Also, find the distance travelled by it during that time.
