- A gun recoils when a bullet is fired

**Q. 4.** A ball is thrown with a speed of 100 m/s at an angle of 30o with the ground. Find the

- Horizontal range
- Time of flight

**Q. 5.** A 5Kg object is moving with a velocity of 10m/s in the x direction. A force of 50N acts on it for 5 seconds. Find the final velocity of the body if the direction of force is

- Same as the direction of motion
- Opposite to the direction of motion

**Q. 6.** 2 cars X and Y take part in a 100Km race. X moves half the distance with a speed of 40Km/hr and the remaining half of the distance with a speed of 60Km/hr . On the other hand Y moves with a speed of 60Km/hr for half the total time and with a speed of 40Km/hr for remaining half of the time. Find the time taken by each car and their average velocities.

**Q. 7.** A man is standing 50m behind a bus. The bus starts moving with a speed of 5m/s and in order to catch the bus the man starts moving with a speed of 10m/s. Find the time taken by the man to catch the bus. Also illustrate the solution with a position time graph.

**Q. 8.** Show that the range of a projectile is same if the angle of projection is 30o or 60o . In which case the range is more.

**Q. 9.** Two forces of 10N and 20N act on an object as shown in the figure. Find the resultant force and its 10 direction. The angle b/w the 2 given forces is 30^{o}
